Assassins are after a prostitute who has come into possession of a cigarette lighter that, unbeknownst to her, contains the negatives that show a politician's assassination. A delightfully playful giallo starring the beautiful Carole Bouquet as Mystère, a high class call girl who becomes the target for a couple of assassins.

In this evocative, atmospheric biography, Roberto Rossellini brings to life philosopher and mathematician Blaise Pascal, who, amid religious persecution and ignorance, believed in a harmony between God and science.
