One or more protagonists encounter another character, who is in company or seems to be busy. Everything seems to be normal, or at least the person encountered seems to be calm or in control. But then, somewhere along the line, the person encountered communicates very quietly — a whisper or a murmur, perhaps just a gesture or a passed note. Their message is short but clear; just "Help Me" or "Save Me", or something on those lines. (In really extreme cases, "Kill Me" is possible.) Then they continue acting as before.
This can be a moment of violent Mood Whiplash, as a situation which seemed comfortable or unremarkable is suddenly shown in a completely different light. The person making the plea is evidently desperate or terrified, probably being watched by a hostile third party, and may be taking a risk just by asking for help. In the worst case, the person making the plea is actually physically injured and maybe close to collapse; they may pass out a few seconds later, triggering a race for medical help or even a tragic death scene. They may even fall over in a way that reveals a previously unseen knife in their back or other serious wound. And even if they aren't hurt yet, they do need that help; if they don't get it, because they were too subtle or the recipient was too dumb, well, Poor Communication Kills.
Very often, though, the trope is Played for Laughs; the person making the plea is out of their depth and desperate, but maybe not in serious physical danger — perhaps they've just made a comedy screw-up which they can't confess too openly, or they're just trapped in conversation with someone terribly boring, but can't get away without seeming rude. The humor may lie in the bizarre methods they try to use to alert others to their predicament, or the other characters being insanely Oblivious to Hints and looking right through their increasingly blatant attempts at hidden communication.
Organised heroes will have a Covert Distress Code to make this more reliable. Alternatively, it may turn out that Everyone Knows Morse when this trope comes into play. An Out-of-Character Alert may achieve a similar or related result. This trope sometimes overlaps with Stealth Insult, when a person held captive insults their captors in a way they can't figure out in order to signal to potential rescuers that they're being held against their will.
- In Fantastic Four #348, Reed is being held hostage by a Skrull disguised as his wife, who has captured the rest of the FF. He tells his robotic secretary, Roberta, that they're just leaving the Baxter Building for a day trip, and to be sure to tell that to her friends in the Marines. Being a robot, Roberta has no friends in the Marines, so she researches the phrase, discovers its colloquial meaning and realises something is wrong. She then finds and frees the rest of the FF, who then rescue Reed.

- There are at a few occurrences in the Discworld series:
"Stranger," said Rincewind levelly. "If you stay here you will be knifed or poisoned by nightfall. But don't stop smiling, or so will I."

- For a more archetypal example, Guards! Guards! has Lupine Wonse, when he is mind-linked to a monstrously powerful and inhuman dragon and trying to act like he's the dragon's willing spokesman; he mouths the words "Help Me" to the head of the Assassin's Guild. As the assassin reflects, there's usually only one kind of help you seek from an assassin...

The man's name turns out to be James Bond.
- In a Nancy Drew Files book, a young woman who has abruptly disappeared calls the gang to assure them that she's okay, telling Nancy to "tell Ned I'll see him at the big rally on Monday". Unfortunately, Nancy thinks that she's reinforcing the message that she's all right and as such, doesn't relay the information to Ned. By the time she finally does, Ned reveals that there isn't any rally planned for Monday, meaning that the girl was trying to invoke this trope.
- In Bravo Two Zero Andy McNab's captors force him to record a video message to show that he is not being mistreated. He remembers part of his SAS training that involved learning to slip uncharacteristic gestures into any such communications, such as constantly running your fingers through your hair if that is not a regular habit. Of course his commanding officers knew better than to believe this sort of propaganda in the first place.
- In the Doctor Who story "Day of the Daleks", the Doctor is held prisoner and then required to reassure the Brigadier that all is well over the telephone. He finds a subtle way to secretly call for help:

Potsie and Ralph come over to see Richie, who answers the door and tells them he can't go out with them or let them in, while drawing "HELP" with his finger on the door.

The burglar gets it though, and explains that Richie is asking for help before dragging Potsie and Ralph in too.
- One episode of Mission: Impossible has agent Jim Phelps secretly held prisoner by a group of townsfolk who are actually all hostile foreign agents.

- In one skit on Reno 911!, Jonesy and Garcia get tacos from a drive-through restaurant that happens to be in the middle of a robbery. They completely miss every hint that the woman at the window tries to give them.

- That Poppy: In the description of the video "I Will Apply The Makeup", the capitalised letters spell out HELP ME PLEASE.
- A comedy version is seen in Ménage à 3, when Kiley meets Peggy and Matt while being carried around by the very strong DiDi. The joke here is that DiDi is seeking medical help for the lightly injured Kiley — but Kiley wants to be saved from DiDi, having just done her a huge favor. DiDi can be terribly over-enthusiastic, and doesn't know her own strength. Also, DiDi is . . . generously proportioned, and severely triggers Kiley's A-Cup Angst.
