Just Before Nightfall
Successful advertising executive Charles Masson becomes involved in a torrid affair with his best friend's wife, Laura. When one of their S&M romps goes bad, Charles strangles Laura to death in a borrowed apartment. With no clues to the crime, police have a hard time finding a suspect. Charles, however, has an even harder time coping with his guilt, his children and his loyal wife, Helene. Directed by Claude Chabrol.
