Le Piège (1958)

In Provence , Father Caillé runs a family pension backed by his daughter-in-law Cora and a maid. The old man persecutes Cora for her assiduity until the day when she, in a particularly violent confrontation, knocks him down before the eyes of Gino, an Italian pensioner of whom she is in love. The two accomplices will try to make up the murder.
