The political overtones in this action-oriented drama may be a little murky outside of its time and place, yet the story is well told. Clement (Jean-Louis Tritignant) is a right-wing rabblerouser married to aspiring young actress Anne (Romy Schneider). He belongs to an underground terrorist group determined to spread chaos among the Western nations in order to eventually gain political control and then expand their activities. At the moment, he is taking part in an assassination scheme aimed at a major labor leader that ultimately fails because of an informer. Clement takes off to find the culprit, leaving Anne in the care of his supposed friend Paul (Henri Serre). That turns out to be a mistake on several different counts.
