Inside a Wall

Go To

Mike: Turns out... someone's living in the walls.
Jay: Whaaaaaat!
Mike: Oh my gaaaaaawd!

You've heard of rats in the walls, but what about people?

Inside The Walls is when a character finds themselves between the walls or ceilings of a building. Reasons for this include:

  1. A character was already inside the wall (doing maintenance, looking for something etc.) when they became stuck.
  2. The character wants to spy on someone (like through a peephole).
  3. The character is using the walls as an alternative route.
  4. Someone has trapped the character in the wall as punishment.
  5. A stray animal like a puppy or kitten is stuck in the wall, or vermin like rats and mice.
  6. Someone traps themselves in a wall to commit suicide.

The trope is often in the comedy genre, since the visual act of being stuck in a wall is so absurd. Another version is when someone is above the ceiling to ogle others creepily, which usually ends with the person breaking through the ceiling. In rare occasions, it appears in the horror genre and the character who is hiding does so insidiously. While this can be comic, that falls under Secret Squatter.

In classic Hollywood fashion, the walls are usually spacious enough for the person to walk around freely. There may even be abundant light that allows them to see perfectly.

Compare Air-Vent Passageway, Chimney Entry, Portrait Painting Peephole, Ceiling Cling.
