->''It is said that the future is always born in pain. The history of war is the history of pain. If we are wise, what is born of that pain matures into the promise of a better world, because we learn that we can no longer afford the mistakes of the past.''
-->-- '''G'Kar'''

In the year 2278, Emperor Londo Mollari looks out on a devastated Centauri Prime as a pair of children, Luc and Lyssa, come wandering in. Rather than throw them out, Londo declares Luc the Emperor for the next five minutes and asks what his command is. [[MundaneWish Luc wants to hear a story]], and Lyssa wants it to be a true story. And so Londo begins telling them a story about humans, a race from a relatively uninteresting sector of space with little military or strategic value so they had gone unnoticed by the rest of the galaxy at large.

35 years before, Londo was on Earth as they began a campaign to expand their sphere of influence, including an expedition to Minbari space. Londo tries to warn them off, but they are adamant. Londo is not the only one with misgivings, as Lt. Commander John Sheridan is not happy with the man chosen to lead the expedition, Captain Jankowski, considering him to be a loose cannon, and not someone to lead a possible first contact.

Light-years away, on the Minbari homeworld, the head of the Anla'shok or Rangers, Lennon, is granted an audience with the Grey Council in an effort to gain support for the Rangers and prepare for the coming of the Shadows. Members of the council are skeptical, unwilling even to send a scouting mission to Z'Ha'Dum, and their leader Dukhat agrees, they will not send anyone to Z'Ha'Dum. They will go themselves.

While they are on their way, Dukhat oversees the initiation of his protege Delenn as the newest member of the Grey Council. Things take a turn shortly after as they encounter a fleet of ships they have never seen before, the Earth Force expedition. The Minbari turn their scanners to full power, which disrupts the Earth ships' jump capabilities, trapping them in normal space. [[MilitaryMaverick Jankowski]], who had been insistent on closing in and getting a good shot of a Minbari ship begins to panic, thinking they had been lured into a trap, and when they realize the Minbari gunports are open he orders his ships to open fire.

The Minbari flagship is severely damaged in the barrage, and [[MentorOccupationalHazard Dukhat is killed]]. His death [[BerserkButton enrages Delenn]], who casts the deciding vote to follow the ships back to their base and destroy them all. From here begins a holy war to [[DisproportionateRetribution exterminate mankind in revenge]]. As the Minbari begin moving on Earth outposts, Gens. Lefcourt and Fontaine brief an assembly of Earth Force personnel. They point out that the Minbari ships are immensely superior to their own and want their people to understand two things, they need a victory to boost morale, and unless they can turn this around, the human race ends with the current generation.

As preparations are made, efforts are being made to gain support for the war effort from other governments. The Centauri rebuff their proposals, but the Narns are willing to supply weapons and a deal is cut.

While the Minbari are enjoying great success, Delenn is not happy. Regretting her enraged decision, she is now looking for a way to stop the war, but Lennon has her go to Dukhat's chamber where she is surprised when she encounters two Vorlons. One of them has a [[DeadManWriting message from Dukhat]] in case of his death, in which he explains that the Shadows are returning to Z'Ha'Dum and in order to win they will need allies, in particular a race known as humans. Now it is imperative that the war be ended before the humans are driven to extinction.

Sheridan is aboard his ship, the ''Lexington'', when they encounter a small Minbari ship. It seems to flame out, but it turns out to be a trap to get their fleet in a pre-determined position, and the [[HyperspeedAmbush Minbari jump right into the midst of them]], doing considerable damage and leaving the ''Lexington'' adrift. Sheridan [[YouAreInCommandNow finds himself in command]] after their captain is killed. Now they are faced with either slowly being pulverized in an asteroid field, or being finished off by the Minbari if they try to call for help. Sheridan decides to lay a trap. He has the crew lay nuclear mines on the asteroids and sends the signal. As a Minbari warcruiser approaches, he detonates the nukes, destroying the ship.

The news is welcome on Earth, especially since that ship, the ''Black Star'', was their flagship. With this victory under his belt, Sheridan is tapped by command for another mission. Delenn has been able to arrange through the Narn for Lennon to meet with representatives from Earth to try and work out an end to the war. Since Sheridan has shown he can handle himself, they want him to be the first one there before they send in a diplomatic team. Accompanying him will be G'Kar, who can speak English and Minbari, and Dr. Stephen Franklin, who is has to either go or sit in a cell for not turning notes on Minbari physiology to Earth Force weapons division.

Unfortunately, the Centauri get wind of it and, thinking it's an arms shipment, send a ship to put a stop to it. Londo, who gave the order, [[MyGodWhatHaveIDone sounds very regretful as he tells this part]]. As the Centauri ship attacks, Lennon is mortally wounded. Before he dies he [[SilentWhisper whispers something to Sheridan]]. When the Minbari arrive they find Lennon's body, and bring Sheridan, G'Kar and Franklin up as prisoners. Sheridan and Franklin are to be executed, but Sheridan tries to tell them something, "I know what's in Dukhat's sacred space."

-->'''Delenn''': What is in Dukhat's sacred space.\\
'''Sheridan''': [[TrustPassword Isil'zha]].\\
'''Delenn''': Let them go. There has been enough death today. \\
'''Franlkin''' Isil'zha? What the hell does that mean?\\
'''G'Kar''': The future.

Unfortunately, the war only gets worse from there. For two years the fighting goes on [[HopelessWar until the Minbari are on the threshold of victory]]. On Earth the president of the Earth Alliance addresses her forces. Intelligence believes that the Minbari will soon attack Earth itself. She calls for all available forces to go up and hold the Minbari off long enough for civilians to escape to neutral space.

-->'''President''': No greater sacrifice has ever been asked of a people, but I ask you now, to step forward one last time, one last battle to [[HoldTheLine hold the line]] against the night. May God go with you all.

As the battle approaches, Delenn goes to see the Vorlons one more time. She is out of ideas, and even though everyone is tired of it, the war has taken on a life of its own. She pleads with them for advice. They simply tell her, "The truth points to itself."

Around Earth, a massive fleet assembles to hold the Minbari off, but they jump right into it, and begin decimating the Earth ships. One fighter, Alpha Leader, is damaged and the pilot, Jeffrey Sinclair, attempts to ram a Minbari cruiser. Delenn, observing the battle, suggests taking a prisoner to interrogate about Earth Forces on the ground if that is to be the next phase. The others agree and she turns around, seeing Sinclair's fighter, and remembers the Vorlons' advice. "That one."

Sinclair's ship is disabled and brought aboard. During their interrogations, they discover something unexpected. The human has a Minbari soul. [[ApeShallNeverKillApe Mibari do not kill Minbari]], and Delenn pleads with the others to end it now. The order to cease fire goes out, but there is still the matter of the human. They decide to have his mind telepathically wiped of his interrogation, and Delenn arranges to keep him close to them, one way or another.

Shortly after the war's end, the Earth president announces a new project, aimed at preventing incidents like the one that lead to the war, called the Babylon Project. It gets off to a rocky start, though, as the unfinished station suddenly explodes.

-->'''Londo''': Of course, as with all good things, it took them a while to work it all out.

With that Londo ends his story, and as the childrens' caretaker ushers them out, Londo pulls up an image of Sheridan and Delenn down in the palace dungeon, as he pours himself a drink.

-->'''Londo''': To the future, my old friends.

!This movie contains examples of:
* AttackOnOneIsAnAttackOnAll: The disastrous first contact causing the death of Dukhat is taken as an assault on the entire Minbari race and they embark on a genocidal holy war of revenge.
* ApeShallNeverKillApe: The Minbari are unique amongst the B5 races in evidently taking this very seriously, which is {{subverted}} via LoopholeAbuse, below.
* AsTheGoodBookSays: Londo's narration misquotes Literature/TheBible, saying that the humans have a saying, "Pride goeth before a fall,"[[note]] The full verse, Proverbs 16:18, reads: "Pride goeth before destruction, and a haughty spirit before a fall."[[/note]] going on to state that the [[{{Foreshadowing}} humans were very proud indeed.]]
* AssInAmbassador: G'Kar, the Narn Regime's representative to the Earth Alliance, who is more than willing to sell advanced weapons technology (stolen from the Centauri) to the humans to use against the Minbari, at vastly inflated prices, in hopes of falsely incriminating the Centauri Republic of supplying an enemy of the Minbari Federation.
** His exact words were that "human currency has been devalued on the interstellar market." If you're on a losing war for the survival of your race/country/planet, your currency will be rendered worthless by others, requiring more to buy the same items. It's economic practicality on G'Kar's part. In fact in the series itself he and the Narn resistance have to buy the same weapons from a human arms dealer, and he remarks the asking price is far higher than what the Narn sold them for.
** That said, he also agrees to broker a meeting between representatives from Earth and an important Minbari official to try and figure out how to stop the war. Depending on how you interpret his character, this could be anything from JerkWithAHeartOfGold to EvenEvilHasStandards (he may have a hate-on for the Centauri, but that doesn't mean he likes the idea of the ''humans'' being slaughtered wholesale by the Minbari.) Or that he's simply an opportunist with a LongGame view on things, and figures having a human race grateful to the Narn for helping save them would be advantageous in the long run. The deal was actually brokered from the ''Minbari'' end, and had the fairly-obvious second message of "we know where the weapons are coming from."
* AndManGrewProud: Pretty much the theme of the movie.
* BalanceOfPower: The primary motivation behind the Narns being willing to sell stolen Centauri weaponry to the Humans to use against the Minbari. If the Minbari track the weapons back to their creators, it will lead them to the Narns' enemies, thus ridding the Narn of the Centauri.
** {{Subverted}} in the {{novelization}}, where the Minbari were perfectly aware of the Narn's plan, and simply didn't care one way or the other, their blood feud being only with the humans.
** Not only in the novelization, but in the movie itself. When Delenn was telling Lennon about the upcoming meeting with parties from Earth who're interested in peace, she tells him that Minbari Intelligence had determined that the Narns were selling Centauri weapons to the humans, and they use the Narns in order to help put together the peace talks (it doesn't end well).
* BeAllMySinsRemembered: Londo's storytelling is interspersed with his regrets over all the hardship he was responsible for, including unintentionally prolonging the Earth-Minbari War, and being personally responsible for the widespread destruction on Centauri Prime.
* BerserkButton: Hurt someone she cares for, Delenn will hurt you. Kill her mentor/father-figure, she will start a war to end your race.
* CallForward: Many, given that this is a prequel that is substantially a ClipShow of flashbacks from the original show.
* TheCameo:
** Claudia Christian playing a young Susan Ivanova in one scene midway through the movie, visiting her brother Ganya and giving him one of her earrings for luck before he deploys during the war.
** Which is a CallForward to the fact that throughout the show, [[TragicKeepsake Ivanova always wore a single earring]].
** Michael York has a blink-and-you'll-miss-it cameo as the weapons officer aboard the EAS ''Prometheus'', the clip being recycled from ''A Late Delivery From Avalon'', the episode he guest-starred in as a ShellShockedVeteran.
** Michael O'Hare has a single scene towards the end of the film as Jeffrey Sinclair (originally TheCaptain on the show itself), leading a squadron of Starfuries at the Battle of the Line and being captured by the Minbari.
* ClipShow: This film was produced, editing new footage in with footage used for flashbacks in the original series, in order to help familiarize new viewers with the show's universe when it jumped networks to TNT.
* CommandingCoolness: John Sheridan, serving as NumberTwo to Captain Sterns.
* ContinuityNod:
** The children Londo tells the story to are Luc and Lyssa Deradi, nephew and niece of [[Recap/BabylonFiveS02E17Knives the late Urza Jaddo]].
** The children's governess is Senna, daughter to recurring character Lord Refa.
** Londo watches the conversation [[Recap/BabylonFiveS03E17WarWithoutEndPart2 Sheridan had with Delenn]] while visiting from the past.
** Londo admits that Luc's answer to "What do you want?" was better [[Recap/BabylonFiveS01E13SignsAndPortents than his]].
* CurbStompBattle: Almost every fight between the Minbari and the Humans. In one battle sequence, we see a sizable fleet of human ships wiped out in ''seconds''.
** CurbStompCushion: The humans win a single battle against a Minbari cruiser, at the cost of most of the task force that ran into it. Otherwise, it is made clear that despite their horrific losses, the humans are making the Minbari ''pay'' in blood for every inch of territory they take.
* DamageControl: After the ''Lexington's'' task force is hit by a Minbari attack, Sheridan begins reading off damage reports to the captain. When Captain Sterns fails to respond to his report, Sheridan turns around to find his superior has been killed, leaving him in command.
* DespairEventHorizon: As the end of the war approaches, Earth is nearing this. Delenn also is nearing it as her ship prepares for the Battle of the Line. She is out of ideas, and her plea to the Vorlons is answered only with a cryptic response.
* DisproportionateRetribution: In return for the death of their religious and political leader, Dukhat, the Minbari set out to wipe out all of humanity.
* DoNotGoGentle: As Londo narrates how hard the Humans fought back we are shown examples of it, including a Starfury chasing and shooting down a Minbari fighter just as two or three other Minbari were shooting at it from behind, a ''Nova''-class dreadnought ramming a Minbari warcruiser in spite of being shot by the same warcruiser at least three times before the contact, and a unarmed human fighting a knife-wielding Minbari warrior, punching it after being downed and ''still trying to stand up and fight after being knifed in the heart''.
* FaceDeathWithDignity[=/=]ObiWanMoment: Londo's story to the children can be seen as both as he knows he will soon die and chooses to tell those who will come after him about one of his greatest failings so that they will not end up like him.
* FirstContact: A human recon expedition into Minbari space accidentally stumbles across a Minbari ship, and are spotted before they can withdraw. A series of misunderstandings leads directly to WeComeInPeaceShootToKill.
* FiveSecondForeshadowing: The Minbari realize their error in using the Warrior Caste's customary greeting towards strangers who might not react kindly to having guns pointed at them (particularly when their stealth technology prevents the humans from knowing whether or not the guns are running hot, and when their sensors accidentally knock out the humans' jump drives), immediately before the humans open fire on them in response.
* ForegoneConclusion: Everyone who's watched the show knows how the war ends, but that doesn't make it seem any less tragic.
* HoldTheLine[=/=]YouShallNotPass: The purpose of the Battle of the Line was to buy time for civilian transports to escape off of Earth. [[http://www.youtube.com/watch?v=KbBRrK9Q-rw The President's final speech makes makes it clear those who fight will likely die]] [[HeroicSacrifice but with their deaths many civilians might be able to escape.]]
* HopelessWar: For the humans. Londo assumes humanity knew this near the start of the war but that did not stop them from fighting. When other species might crumble with despair, the humans reforged their efforts and made the Minbari taste blood at every inch. There are plentiful examples on this page of just how hard Humanity fought against the odds.
* HumansAreWarriors:
-->The humans, I think, ''knew'' they were doomed. But where another race would surrender to despair, the humans fought back with even greater strength. They made the Minbari fight for every ''inch'' of space. In all my life, I have never seen anything like it; they would ''weep'', they would ''pray,'' they would say goodbye to their loved ones... and then throw themselves, without fear or hesitation, at the very face of death itself. Never surrendering.\\
No one who saw them fighting against the inevitable could help but be moved to tears by their courage... their stubborn nobility. When they ran out of ships, they used guns. When they ran out of ''guns'', they used... knives, and sticks, and bare hands. They were... ''magnificent''.\\
I only hope that when it is my time that I may die with ''half'' as much dignity as I saw in their eyes in the end. They did this for '''''two years'''''. They never ran out of courage... but in the end, they ran out of ''time''.
* HyperspeedAmbush: The Minbari have actually made it a standard tactic. They lure Earth warships into a predetermined position then jump right into the middle of them. The vortex itself is devastating to any ship caught near it, and then the Minbari proceed to carve up whatever's left.
** Another happens when the Centauri interrupt the attempted peace meeting. They emerge from the jumpgate and destroy the Narn cruiser before it can identify them, then fires on the planet, killing the Minbari representative and ruining the only chance to end the war.
* HyperspeedEscape: Attempted by Captain Jankowski's scout expedition after they are spotted by the Minbari, but fails due to the Minbari's scanners inadvertently disrupting their jump engines.
** Once they have disabled the Grey Council's starship and stopped the scanners, the human fleet proceeds to make good their escape. The Minbari proceed to follow them to their base and KillEmAll.
* JustAStupidAccent: The French-accented Centauri nursemaid in the framing story stands out quite glaringly among every other Centauri we ever hear. In the Centauri Prime Trilogy, she is a major character and is described as having a "northern" accent.
* KarmicNod:
-->'''Londo''': I know my sins, and the price I will eventually pay for them.
* LateArrivalSpoiler: Chronologically, this show takes place before anything else in the series, but if you watch it first, it ''will'' spoil many important plot points throughout the first four seasons of the show proper.
* LoopholeAbuse: When they determine that Sinclair has a Minbari soul, Delenn [[ApeShallNeverKillApe uses that as an excuse to stop the war]].
* MeaningfulName: The ship that makes first contact with the Minbari, starting the war that nearly wipes out humanity, is named for Prometheus, the Titan from Myth/GreekMythology who stole fire from the Gods to give to man, and was punished severely for it.
** Delenn of the Family Mir, was given a PunnyName by Creator/JMichaelStraczynski, based on a BilingualBonus: "Mir" is Russian for "Peace." The fact that she's played by '''Mira''' Furlan might also have influenced the name.
** Lennon's name was specifically chosen by JMS to reflect his role in the story: [[Music/TheBeatles all he was saying was "give peace a chance"]], after all.
* MentorOccupationalHazard: Dukhat.
* MilitaryMaverick: Captain Jankowski, regarded by Commander Sheridan and other officers as being a "loose cannon." [[DeconstructedTrope Inadvertently starts the Earth Minbari War.]]
* MomentOfWeakness[=/=]ATragedyOfImpulsiveness: Right after Dukhat is killed, Delenn in her grief, angrily orders the extermination of the humans. When she finally calms down, [[MyGodWhatHaveIDone she is horrified by what she has done.]]
* MundaneWish: When Londo tells Luc he may give any one order he pleases with the authority of the Emperor and asks him [[ArcWords "What do you want?"]], Luc asks Londo to tell him a story. When Senna chastises Luc for wasting his wish, Londo ruefully notes that Luc's answer to that question was much better than [[Recap/BabylonFiveS01E13SignsAndPortents his]].
* MyGodWhatHaveIDone:
** Delenn carries this all the way to the end.
** Londo describes going through this years later, when he learned that he was responsible for prolonging the war by ordering an attack on an attempted truce brokerage between the Earthers and the Minbari (brokered by the Narn), mistaking it for a weapons deal between the Earth Alliance and the Narn Regime.
** In the novelization, Captain Jankowski commits suicide; the note he leaves behind simply reads, "On my head."[[note]]And the narration [[DeadpanSnarker dryly notes]] the irony of this, considering that the Captain's choice in suicide method left [[BoomHeadshot little of his head to rest anything on.]][[/note]]
* NoodleIncident: The Omega Incident. A number of officers feel that [[MilitaryMaverick Captain Jankowski]] was responsible for whatever went down there, but he was officially cleared of responsibility by the authorities.
* NuclearOption: How Sheridan defeats the ''Black Star''.
* PragmaticAdaptation: The Soul Hunters were heavily involved in the beginning of the war in the show, a sighting of one their ships cluing Dukhat into the impending disaster just a moment too late and their subsequent boarding attempt to claim his soul being part of why emotions ran so high when the decision was made. They are neither shown or mentioned in the movie, which given they have no further bearing on events is probably wise.
** [[WordOfGod JMS]] says that showing the Soul Hunters would have been too confusing to new viewers unless they took 15 minutes to set it up, which they couldn't fit in. They do appear in the novelization along with a scene in which a wall of Minbari try to prevent them from taking Dukhat's soul.
* RockBeatsLaser: Human weapons and technology are far inferior to what the Minbari have. That said, nuclear weapons still prove to be quite effective once you manage to get the enemy close enough to the warhead to be caught in the blast. Sheridan does this by way of jury-rigged SpaceMines in an AsteroidThicket. Mind you, this is the ''[[CurbStompCushion only time]]'' in the war that any human commander ''wins'' a battle against the Minbari until the end of the war.
* SilentWhisper: We don't find out what Lennon said to Sheridan until he tells it to Delenn. "Isil'zha."
* SpaceMines: Sheridan mines the AsteroidThicket around his crippled ship, using the ship's magazine of tactical nuclear warheads, before sending out a distress call. When the ''Black Star'' returns to finish off the surviving ship, Sheridan sets off the nukes.
* SufficientlyAdvancedAlien: The Vorlons.
* TrustPassword: After the attempt to end the war ends with a surprise attack, Lennon tells Sheridan something to say to his people. When they arrive they find Lennon's body and bring Sheridan, Franklin and G'Kar aboard. Sheridan tells them what is in Dukhat's sacred space (''Isil'zha'', the future), which prompts Delenn to let them go.
* WeComeInPeaceShootToKill: Subverted: Neither side intended to start a fight, but [[NobodyEverComplainedBefore nobody told the Warrior Caste]] that revealing your weapons is considered a ''threatening'' gesture by the humans, who panic and open fire.
* WholeEpisodeFlashback: The entire movie is Londo telling a story to a couple of children.
* YouAreInCommandNow: Commander Sheridan finds himself in command of the ''Lexington'', after the death of Captain Sterns.
** Also played with, as Londo makes Luc emperor for five minutes.
