Returning to a night club where he forgot his sweater the night before, Michel Jussieu (Maurice Ronet) is the involuntary witness to the murder of a far right-wing journalist. He recognizes the murderers — Eleonore (Nicole Berger) and Patrice (François Maistre), members of a secret political organization he has known since the resistance years. When he is accused of the murders, Michel cannot bring himself to reveal the truth.
