"Alfred Hitchcock Presents" Place of Shadows (1956)

A young man is picked up at a train station, taken to a nearby monastery, and met by Father Vincente, who is in charge of the monastery. The visitor introduces himself as Mr. Unser, and asks to see a friend named Rocco who is temporarily being cared for by the monks. But the priest realizes that the visitor is not Unser, but rather Clements, who blames Rocco for robbing him and ruining his life. Knowing that Clements has come for revenge, the priest returns the money that Rocco stole from him, but refuses to let him see Rocco. The priest urges Clements to forgive Rocco, but the young man remains consumed by hatred and anger, and persists in his efforts to gain revenge.
