About
"A nightmare built from one small bad decision"
A directionless young man borrows his father's taxi for one night out and wakes up next to a dead body with no memory of what happened. What follows is a slow, unsettling descent through interrogation rooms, prisons, and courtrooms as he tries to prove his innocence in a system that seems more interested in efficiency than truth. It's tense, bleak, and deliberately paced, carried by a raw lead performance and a creeping sense of dread rather than twists or action.
Watch it for
a devastating lead performance charting innocence eroding under institutional pressure.
Maybe skip if
you need warmth, humor, or a fast pace to stay engaged.
