To bolster his social status, he has a mistress to liven up his Saturdays. But nothing is going right. His wife Marion exasperates him, his children irritate him, his job gives him no real satisfaction, his mistress neglects him and his superior, Monsieur Gambaud, gets on his nerves. But when he meets a beautiful young secretary, his life and habits are turned upside down: Blanchard amuses him and gets his way. In revenge, Gambaud warns Blanchard's wife.

In this French-language film, Albin is a mercenary soldier. Sure, he's paid to kill, but he only agrees to jobs where he's killing those who need to be killed. Anyway, he trusts his buddies, and they trust him: in this case with a big haul of money they found in a jungle shoot-out. When he returns to France one of the first things he does, quite by chance, is to go see the act of Le Grande Magic Circus. The circus keeps coming into his life for the rest of the movie, as he tries to live a "regular" life.

A father plans to kill in the same day the nine members of the jury who condemned his son to death.
