When the American painter Jeff Farrell (Kerwin Mathews) dumps his girlfriend in Camarga, France, he meets the eighteen year-old waitress Annette Beynat (Liliane Brousse) in a bar and decides to stay in the town on vacation at a bed and breakfast owned by her stepmother Eve Beynat (Nadia Gray). Jeff feels a great attraction for Annette but soon he is seduced by Eve and has a love affair with her. He learns that three years ago Annette was raped by a man called Janiello (Arnold Diamond) and her father Henri (Donald Houston), who is locked in an asylum, killed the man using an acetylene torch. After visiting Henri, Eve tells to Jeff that he accepts to let her go with him provided they help him to escape from the asylum driving a runaway car to the harbor. Jeff decides to help Henri but soon he is visited by Inspector Etienne (George Pastell) and discovers dark secrets.
"Maniac" is a combination of film-noir with psychological thriller by Hammer having a triangle of love to complete the big picture. The sexual tension between Henri, Annette and Eve is constant and the relationship of Henri with the two women is unusual and strange. The plot has many twists and is engaging. My vote is seven.
