In a Quebec prison in 1952, Bishop Bilodeau accedes to an unusual request to hear the confession of an aging convict. On entering the prison chapel, Bilodeau finds himself locked inside, held against his will, and forced to watch as the inmates stage an elaborate play - a recreation of events from forty years earlier, when Bilodeau and the confessor, Simon, were locked in a love triangle with another boy, the beautiful Vallier.
