When a group of people in distress are stuck in one place, they will usually send someone to Bring Help Back. They might be suffering through The Siege, stuck in a Closed Circle, or they're too sick to travel and need someone to Find the Cure!. For whatever reason, people are in danger and no one is coming to save them. So what do they do? If no Epic Hail is available, then they'll have to send one of their own out to get the help they need.
Similar to Gondor Calls for Aid, except that the process of calling is an adventure in and of itself. Typically, the nature of the threat is such that securing help is an Instant-Win Condition — provided you reach them in time, anyway. Compare Pet Gets the Keys for another task commonly accomplished by the Non-Human Sidekick. See also Bring News Back, which is sort of an inverse (bringing news to someone to help them instead of bringing them news that you need help).
- The main struggle in My Little Pony: The Movie (1986) is the journey to Flutter Valley to petition the Flutter Ponies for aid against the Smooze.
- In Golden Films' Thumbelina, the protagonist has to send for the prince so he can fix the dam.
- In the very beginning of Yellow Submarine, the attack on Pepperland courtesy of the Blue Meanies compels the country's lord mayor to send Old Fred off in the titular submarine in search of help.
- A Bug's Life has Flik venturing out to find warrior bugs to bring back to help defend the colony.
- Alive has two of the survivors crossing the Andes mountains in search of rescue after it's clear that no one is coming for them.
- Seven Samurai has a couple of farmers go to a city in order to enlist help from masterless samurai. Because they're poor, the elder advises them to find "hungry samurai", and eventually they do.
- A Taxi Driver has the besieged citizens of Gwangju pleading with Peter (actually Jürgen Hinzpeter, journalist for West German broadcaster ARD) to take the footage of the ROK military massacring them out of the country and tell the rest of the world, as the South Korean broadcasters are censoring all of the events at the behest of the military dictatorship as merely communist-provoked rabble and vastly downplaying the kill count.
- In With Fire and Sword, the first book of the Sienkiewicz Trilogy, two main characters end up on a virtual suicide mission to get through enemy lines in order to summon the Polish army to help their position under siege.
- In the Knight and Rogue Series when Michael and Fisk realize there's no way the two of them will be able to escape capture by Ceciel's guards Michael makes himself the most noticible thing imaginable after giving Fisk the orders to run for it and let someone know he's been abducted.
- In This Rough Magic, Benito slips out of the impenetrable fortress of Corfu, past the Hungarian siege lines, and all the way north to Venice to summon help. Then back south and past the siege and into the impenetrable fortress again to tell them help is on the way. Then back out again...
- Happens in Warrior Cats. In Dawn of the Clans: The First Battle, Clear Sky and his cats trap Thunder, Gray Wing, Tall Shadow, and Jackdaw's Cry on top of the Great Rock at the Four Trees. Thunder manages to escape, and has to get back to the Moor Group so that he can bring cats back to save the other three. This involves a harrowing Chase Scene.
- In This Immortal, when Conrad and Hasan are stuck in a Hot Spot while tied to stone pillars with no way to free themselves, Conrad manages to talk his dog Bortan into going and fetching help. Or at least he hopes the dog understood him.
- In the Star Trek: Voyager episode "Basics," our heroes are under attack by the Kazon (a common occurrence for the first two seasons, but this time it's worse than ever). Tom Paris is able to take a shuttle out of the battle zone and call for reinforcements from their Talaxian allies.
- Game of Thrones. In "Beyond the Wall", our heroes are trapped in the middle of a freezing lake by the Night King's army of undead wights. Gendry, the least experienced fighter, is sent to Eastwatch so an Instant Messenger Raven can be dispatched to Queen Daenerys in the hope that her dragons can pull a Big Damn Heroes before the lake freezes over. They do, sparking off a massive fan debate over whether the math works out.
- A variation in Galavant: Sid decides he has to atone for killing Galavant (he gets better), although he isn't sure what he must do. In the finale, he returns to the battle between Richard and Galavant, the Hortensians, and the Valencians with reinforcements made up of the various Wacky Wayside Tribes Galavant and co. found throughout the season (although not the guest stars who headed said tribes, because as Sid pointed out, that would be too expensive for the network).
- The Elder Scrolls IV: Oblivion lets you do this in an optional quest; the city of Bruma is under attack by an enormous Oblivion Gate, and you can request help from the other cities in the province (which they'll send, but only after you close the gates threatening them, first).
- Mass Effect 3 is pretty much Bring Help Back: The Game. You spend much of the game rallying any help you can think of and also solving several conflicts along the way to free up the conflicting parties' war resources, so you can take back Earth from the Reapers.
- Partly the case in Dragon Age: Origins, although there's no one particularly waiting for you to bring allies, as the original defenders are dead, and no one trusts the Grey Wardens anymore thanks to Loghain. Much of the game, however, does revolve around going around Ferelden and securing help, including Dalish elves (or werewolves), dwarves, (possibly) golems, magi (or templars), etc. Naturally, these will agree to send help only if you help them first. Oh, and you still have to convince the Fereldens to trust you again, so that the Ferelden army can join you.
- Basically the goal of every playable character in season one of Telltale's Game of Thrones. House Forrester is on the verge of war with House Whitehill, and after Lord Forrester is slaughtered at the Red Wedding his squire and children desperately try to get help wherever they can. His squire Gared joined the Night's Watch in an attempt to find a legendary grove said to hold the secret to saving their house, his eldest son Rodrick attempts to marry into a stronger house to gain an army while dealing with Whitehill occupation at home, his eldest daughter serves as Queen Margaery's handmaiden and attempts to enlist the aid of the Tyrells and Lannisters, and his second son Asher attempts to return with an army after having been exiled.
- The only way to unlock the Golden Ending of A Dance with Rogues is to give your word to bring back help to the Delberg Castle, besieged by the orcs in the endgame, and make good on that promise.
- The objective of most of your journey in Metro 2033 is to travel through dangerous tunnels to reach the largest station in the metro in order to ask the Rangers for help against the mysterious Dark Ones that threaten your small home station. They aren't willing to help as much as you hoped, though.
- Drow Tales has a villainous version. As of the Time Skip, the ruling clan of Chel'el'sussoloth, the Sharen, has angered so many people and built up so many enemies, that they are being overwhelmed by the Sarghress and Sullisin'rune clans. In order to preserve their crumbling empire, Zala'ess Vel'Sharen goes on a diplomatic mission to the city of Nuqrah'shareh in hopes of recruiting like-minded Blue Bloods with promises of conquest. Her mission is ultimately a success, and picks up enough allies to completely turn the tables on the rebels, just as her sister, Sarv'swati, is about to face her Last Stand.
- During the Battle of Atollon at the end of Season 3 of Star Wars Rebels, the Rebels are pinned down by an Imperial fleet commanded by Grand Admiral Thrawn. Commander Sato launches a kamikaze attack on an Imperial Interdictor, allowing Ezra Bridger to escape and get their Mandalorian friends to come to their aid.
- During the siege of the Alamo, a number of couriers were sent out of the fort to bring back reinforcements. They didn't make it back in time.
- Before the Battle of Marathon against the invading Persians, Athens sent Pheidippides, their fastest runner, to Sparta for reinforcements, a considerable distance which he covered in two days, allegedly with a time out to stop and chat with the terrifying wilderness god Pan. The Spartans didn't actually show up in time for the battle, so the Athenians defeated the Persian force with the help of only the tiny city of Plataia (and Pan, apparently.) An embroidered account claims that Pheidippides subsequently ran from Marathon to Athens and expired with the news of the victory on his lips, which probably apocryphal story eventually gave us the modern English word "marathon" in the sense of 'long-distance run'.
- The Alive example was a dramatization of a true story that occurred in 1972.
- The Donner Party, snowbound in the Sierra Nevadas, running out of food and losing people to malnutrition, sent a group called the Forlorn Hope to Sutter's Fort in the Sacramento Valley to seek help. The 100-mile trek... did not go well. It's debated among historians how much the Donner Party really did resort to cannibalism and how much was sensationalized in the newspapers, but the Forlorn Hope is generally agreed to have done it.
