Five Numbers! (2011)

Plot

The prison holds just four inmates and a stray cat. A sudden blackout trips every lock, setting the men free. Yet no guards appear, and every exit has vanished. Puzzled, they wander the empty halls until the oldest prisoner begins acting oddly—muttering, tracing symbols on the walls. His strange ritual triggers something unexplainable, warping the prison’s reality and revealing a truth far darker than their confinement.
