Message in a Bottle

Go To
"Damn it, I forgot to ask for cheese-filled crust on the pizza!"
"I'll send an SOS to the world
I hope that someone gets my
I hope that someone gets my
Message in a bottle..."

So things are looking pretty grim. A character is trapped somewhere terrible, usually an island in the middle of an ocean, a slave ship, or somewhere that it just plain sucks to be and there's no way to get a message to anyone. In this desperate situation, the only hope possible is a futile grasp at straw. Take a bottle, put in a hastily written cry for help and hope that somewhere, someone, somehow manages to find the bottle and lend a hand.

Lucky thing the odds of this happening are a Million to One Chance, or else this wouldn't be much of a storytelling device.

Despite the obvious problems with this trope, it still retains a fair amount of popularity, due to some advantages that it confers. First, the Message in a Bottle is such a desperate ploy for help that a character really has to be scraping the bottom of the barrel to even try it. It reeks of desperation. Second, usually the people who receive the message are completely unknown to whoever sent it, so their decision to help the sender of this random note from the middle of nowhere helps establish that they are, without a doubt, the good guys. Third, it's a workable Framing Device, both in the sense that the message spurs all the action of the story but also that the message can relate all of the action of the story, if the note turns out to be detailed.

It also shows up fairly often for completely different reasons, as the Message in a Bottle itself is a well-known staple of fiction. It's nearly a Discredited Trope, for that matter, but not quite yet. This appears to be somewhat related to Apocalyptic Log.

Sister Trope to Island Help Message. Related to Deserted Island.

  • A variation in Castaway on the Moon. Seong-Geun is marooned on an island—under a bridge, in the middle of Seoul (It Makes Sense in Context). He writes "HELP" on the sand, which is observed by Jung-yeon when she spots him from her apartment on the far side of the river. But she's agoraphobic and far too shy to actually come to his island and talk to him, so she drops him notes from the bridge, inside bottles.
  • The Louis de Funès comedy Sur Un Arbre Perche uses an unusual variation. The three main characters are trapped on a tree growing from a seaside cliff, and put a message in a bottle with a small parachute. The bottle lands safely on a café table, but the rescuers aren't sent just yet because the café owner is adamant that the table pay for the two clearly empty bottles even though they only ordered one.

  • The premise of the Planet of the Apes novel is that a couple on an intergalactic cruise ship finds the whole story written and put inside a bottle that's out IN SPACE!, combining this trope with Direct Line to the Author and Sci-Fi Writers Have No Sense of Scale.
  • The Nicholas Sparks novel as well as The Film of the Book of the same title.
  • A message in a bottle is discovered at the end of And Then There Were None by Agatha Christie. The author of the message claims to have gotten the idea from adventure stories.

Turns out the submarine had an unfortunate run in with a vengeful sea-hag, and the submarine's Admiral, the final survivor, is the writer of the message. The story literally ends with him saying he needs to get the message in a bottle before it gets wet, moments before the submarine gets filled with water and drowning him.

  • The framing device of Yosl Rakover talks to God is that the novella is a crossover prayer/diary written by holocaust victim Yosl Rakover, hidden in a basement in the ghetto of Warsaw, and found after the war. In reality, it was written in Argentina in the late forties by Zvi Kolitz, and Yosl Rakover is a fictional character. This important fact was dropped in some inofficial reprints, leading people to believe that the framing story was true, something the author never intended. When faced with the existence of an author, many chose to denounce the story as a fraud, rather than laud it as a marvelously insightful piece of fiction. A meta case of Misaimed Fandom?
  • In Winnie the Pooh a flood threatens Piglet's home so he sends out a message in a bottle hoping for help. Pooh spots the bottle but can't understand the message, so he sets off to find Christopher Robin and they both go to Piglet's rescue.

    • This trope serves the basis of the very first story Lovecraft wrote, at the tender age of seven. It's ultimately subverted, with the whole thing being an elaborate practical joke. The prankster was at least kind enough to leave $25 to pay off the expenses of the rather unhappy treasure hunters' trip.
  • 20,000 Leagues Under the Sea: Captain Nemo plans to use one to assure his research is not lost:
    "Here, Professor Aronnax, is a manuscript written in several languages. It contains a summary of my research under the sea, and God willing, it won't perish with me. Signed with my name, complete with my life story, this manuscript will be enclosed in a small, unsinkable contrivance. The last surviving man on the Nautilus will throw this contrivance into the sea, and it will go wherever the waves carry it."
  • The Star Trek Expanded Universe novel Ship of the Line used a version of this, except the "bottle" in question was a message probe with a delay. As the USS Bozeman is being chased by a Klingon cruiser, The Captain wishes to notify the Enterprise (as Bateson calls it "a true ship-of-the-line") of the presence of the cruiser, but the Klingons are jamming all frequencies. The probe is launched with a recorded message set to broadcast as soon as it leaves the range of the jamming field. Unfortunately, by the time Kirk arrives to chase off the cruiser, the Bozeman has already entered the temporal anomaly that would send it on a collision course with the Enterprise-D. It did, however, save thousands of lives on the defenseless outpost in the sector, which the Klingons planned to destroy.
  • The Twenty-Eighth Voyage of The Star Diaries is Ijon Tichy's diary of his last and longest voyage, which he put in "an empty barrel of oxygen" and let drift into space.
  • The plot of In Search of the Castaways begins when the protagonists find a bottle in a shark's stomach, which contain a call for help in several languages. Unfortunately, the message is incomplete enough that they only have the latitude to go on, and need to sail around the entire globe to find the sender.

Instead, he tells her and Jon to write to the Seamen's Mission at the home port of Eric's ship so he can collect the letters every time the ship returns to Scotland.
  • A cartoon in Will Eisner's Star Jaws depicts a space patrolman finding a message in a bottle which says "Help! I'm a prisoner in a fortune cookie factory."

  • In Lost, four survivors set sail on a raft, attempting to secure rescue. They take along a bottle containing messages from the rest of the survivors to their families. When the raft blows up, the bottle returns to the island with the tide, alerting those still on the island that something has Gone Horribly Wrong on the raft. This is a rare instance of the bottle returning with the tide, which is possibly a more likely outcome than the bottle actually reaching other people.
    • As revealed later, the island can only be entered and exited on certain bearings, so the bottle (and the raft) was going to return to the island anyway.
  • One episode of the Swedish Pippi Longstocking television show had the eponymous character asserting that her father had been captured by pirates because he sent her messages with bottles — something which most of the townspeople understandably regard as being utterly preposterous. But this being a children's show, this is naturally exactly what has happened.
  • On Gilligan's Island Mary Ann had a fake boyfriend on the mainland she pretended to communicate with in this way.
  • In See, once the blind Alkenny tribe start living at their second settlement, traitor Gether Bax, still eager to get rid of the "witches" (sighted people) in the tribe, drops rope messages in plastic bottles in the nearby river to give their position away to the Witchfinders.

  • Survivorman is a Canadian reality show in which the star, Les Stroud, is dropped into various environments to survive for 7 days with no equipment. One episode was based around him being in a life raft in the middle of the ocean, followed by being beached on an island. Les then invokes the trope and actually throws a message in a bottle into the sea, with him even highlighting the last ditch, utter desperation of such an act. Possibly subverted though, because at the end of the episode, a message states that while he put his cell phone number on the message, nobody has ever phoned in.
  • Star Trek: Voyager:
    • In "Eye of the Needle", Voyager makes contact with a Romulan scientist in the Alpha Quadrant, only to find they're communicating twenty years back in time. In order to avoid changing the timeline, he agrees to take their messages and pass them on to Starfleet twenty years later. But the crew knows from their records that the scientist will die four years before this happens, so they've no way of knowing if he made arrangements in case of his death, or even if the Romulan government would have allowed him to pass the information on.
    • In the appropriately titled "Message in a Bottle", the holographic Doctor is the message and the bottle is an alien Subspace Ansible network that's widespread enough to reach a Starfleet vessel on the very edge of Federation space.
    • "Course: Oblivion" has the crew of the biomimetic copy of Voyager try to send one in the form of a probe to the real Voyager in the case that they don't survive their journey home to the Demon-class planet, but unfortunately it was destroyed upon launch.
  • The Haven episode "The Trial of Audrey Parker" included a clever adaptation of this trope; Audrey Parker was trapped on a boat heading out to sea and had already gone out of range of the cell towers. Instead she sent a text message, and her phone naturally began repeatedly trying to send it. She then dropped it into a bottle and shoved it out the porthole where it drifted with the tide back to shore until getting back into coverage range, when the message was sent.
  • The Twilight Zone (1985): In "A Saucer of Loneliness", the small eponymous saucer arrives on Earth and passes on its message to an extremely lonely woman named Margaret, who refuses to divulge its contents to anyone. However, she does make several copies of the message and puts them in bottles that she throws into the ocean. A man finds one of them and stops her from killing herself. He then reveals that he knows what the message said:
    "There is, in certain living souls, a loneliness unspeakable, so great it must be shared as company is shared by lesser beings. Such a loneliness is mine. And know by this that an immensity is one lonelier than you."

  • The page quote comes from the song "Message In a Bottle" by The Police. It's used as a metaphor for reaching out for help in times of loneliness, and contains the moral that everyone feels this way at some point in time.
  • One interpretation of The Cruxshadows' "A Stranger Moment" is of a doomed sailor on a sinking ship sending out one of these for his loved ones.

  • In the original The Hitchhiker's Guide to the Galaxy (1978) radio series, Arthur Dent and Ford Prefect are stranded on prehistoric Earth, and attempt to attract the attention of a passing spaceship by waving a towel at it. A volcano then erupts, covering the towel with lava. When the Earth is blown up six million years later, the now-fossilized towel gets launched into space and found by Zaphod Beeblebrox in the spaceship Heart Of Gold, who travels back in time and rescues them. (Things like this tend to happen whenever you use the Heart Of Gold's "Infinite Improbability" drive.)

  • In the 2001 Mata Nui Online Game, it is said that the Book of Chronicles could become this if the island gets destroyed, making this video device that plays back the game's cutscenes the last reminder of its inhabitants, sent floating in the ocean.

Anyone found uncorking a bottle with a message in it in Elizabethan England is guilty of a capital offence.
  • A German boy tossed a bottle into the Baltic Sea, and a Russian boy found it on a beach 24 years later.
  • Older Than Radio: The first verified user of this trope is Chunosuke Matsuyama, whose ship crashed on a Pacific island in 1784 while they were searching for buried treasure. Before they all starved to death, Matsuyama carved their story in wood and floated it in a bottle. His message took 151 years to wash ashore — ironically in Hiraturemura, the Japanese town where Matsuyama was born.
  • Researchers who release things into the air or water - free-floating weather balloons, rehabilitated or tagged wild animals, colored floats to trace currents or underground streams - will often label them with an ID code and toll-free phone number or e-mail address, with the expectation that people who find them later may report where the object of their study turned up.
  • Defectors who've escaped North Korea have sometimes resorted to attaching messages to balloons and releasing them when the wind is blowing back across the border, for lack of any other way to inform their relatives that they made it out alive.
  • In 1777, Henry Whiteside found himself trapped in his own lighthouse on the Smalls Rock by gales during what was supposed to be a brief visit. Supplies were low, and he deperately put a distress message in a bottle and cast it into the sea. It had a note for the finder about who to send it to, and, incredibly, the intended recipient got the message just two days later. Whiteside and his companions were rescued soon after.
