Marina (Romy Schneider) and Claude (Gabriele Tinti) have a violent argument after leaving an inn in the French countryside. A pistol is fired, Claude roughs up his girlfriend and the couple speed off in a convertible. The car leaves the main road and races along the cliffs of the Brittany coastline until it plunges over a ledge into the sea below with Claude at the wheel. Among the hillside rocks, we see Marina, who miraculously escaped from the car and is the only witness at the scene. All of this unfolds under the opening credits of Qui? (1970), a rarely seen French film which offers some odd twists and turns in its brisk 73-minute running time (In some regions it was released under the title The Sensuous Assassin, which is completely misleading in regards to the actual storyline).
