Requiem for a Handsome Bastard(1992)

Original title: Requiem pour un beau sans-cœur

Despite the fact that he is completely unrepentant about his crimes, when Regis Savoie's son asks to visit him, prison authorities grant permission for the boy to come. The thief and murderer (Gildor Roy) takes advantage of the moment of his son's arrival to steal a gun and take flight. He settles some old scores, gets together with his girlfriend, and heads for the hills, pursued by a detective who is not to be swayed in his efforts to follow and recapture him.
