Coup de tête

Noël Guiscard, who served as an officer in Africa, has now become a mere salesman. But, being the sporty type and wishing to fight against crime and injustice, he has the idea to create "La Sauvegarde", a society involving boxers and wrestlers without commitment, meant to defend its clients against menaces of any kind. His friend Colette lets him know that Lambercier, the president of the "Consortium Immobilier" is being blackmailed by a former associate.
