Four college roommates begin experiencing something they can’t explain—individually.

A smell of smoke with no source. Footsteps in an empty hallway. A voice that doesn’t belong.

Each of them dismisses it. Stress. Exhaustion. Imagination.

Until one night, they all hear it at the same time.

Three knocks.

What follows is not a ghost story in the traditional sense, but a shared encounter that forces them to confront something far more unsettling: a presence that doesn’t just linger… but waits.

As they begin to piece together what happened in the house before they arrived, a pattern emerges—one tied to a fire, a child, and a hallway that was never fully left behind.

Told in a restrained, confessional style, Three Knocks explores what happens when a space holds onto the last moment it was needed most.
