maniac (1963)

Taking violent revenge for his daughter Annette's rape sees Georges incarcerated in an insane asylum. A few years later an American stumbles on, and decides to stay in a village, in part due to his attraction to Annette. A tug of love ensues between the daughter and her mother, for the American. Further intrigue happens when Georges escapes.
Set in the Camargue, it conveys a sense of the heat and dust, but soon loses it's way, and the initial promise dissolves into little more than a pot boiler.
