The Afternoon of a Torturer

The Afternoon of a Torturer is a 2001 Romanian biography film directed by Lucian Pintilie. It recounts an interview with Franț Țandără, a parricide and a torturer in the Communist jails, who openly confesses to the terrible crimes he committed in his youth. Out of the estimated 1,700 Romanians whose mission under the regime was torturing political prisoners, Țandără was the only one who felt a need to confess.
