Vahid, an unassuming mechanic, has a chance encounter with Eghbal, a man he strongly suspects to be his former sadistic jailhouse captor. Panicked, Vahid gathers several former prisoners, all abused by that same captor, to try and confirm Eghbal's identity. As the bickering group drives around Tehran with the captive, they must confront how far to take matters into their own hands with their presumed tormentor.
