1942. The adventure of 3 men on a mysterious island.

The film tells the story of Françoise Frémont, who travels across Europe on an apparently random killing spree, bumping off a series of increasingly odious men. From Swinging London to the eternal city of Rome, she leave a trail of dead bodies and the question: why? A mystery film as only Jean Louis van Belle could make it, The Lady Kills is a blast from start to finish with an amazing soundtrack of gloriously groovy psych-rock.

Having fortuitously discovered a photograph in which Marthe embraces someone unknown, Étienne Dorsay becomes jealous and imagines various stratagems to identify the lover. In the meantime, he and his friends acquire a weekend house for a very low price.

Renée dite Guinguette, a former prostitute, has earned enough money on the Parisian sidewalk to buy her dream: a waterfront guinguette. Her new lover, Marco, offers her the use of an unused adjoining barn to store the second-hand cars he trades in. But the "used" cars are actually stolen, and the charming Marco is a bad boy. After a few deaths and various vicissitudes, love finally triumphs.
