Screenwriter Philippe (Duchaussoy) imagines a crime committed by his wife Sylvie (Delon) and a mutual friend Pierre (Serre): a dead body is put in a trunk but the hand sticks out. Sylvie and Pierre begin to have an affair and things get very dangerous and the imaginary crime is on its way to becoming prophetic.
