The Lady Kills (1971)

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.
