L'amour avec des si (In the Affirmative) (1962)

The film is a road movie that follows a middle aged man who gives a young woman a lift. On the car radio, news bulletins warn the population against a recently escaped sadist who is known to prey on young women and children. Lelouch often cuts away from the main story, if only briefly, to parallel events that are not necessarily crucial to the story but illustrate what is suggested by the radio.
