The second part of the Seventh Company adventures.

The whole clique of Cruchot's police station is retired. Now he lives with his rich wife in her castle - and is bored almost to death. He fights with the butler, because he isn't even allowed to do the simple works. But when one of the clique suffers from amnesia after an accident, all of the others reunite and kidnap him, to take him on a tour to their old working places and through their memories. In their old uniforms they turn St. Tropez upside down.

The ambitious police officer Cruchot is transferred to St. Tropez. He's struggling with crimes such as persistent nude swimming, but even more with his teenage daughter, who's trying to impress her rich friends by telling them her father was a millionaire and owned a yacht in the harbor.

The cruel and abusive headmaster of a boarding school, Michel Delassalle, is murdered by an unlikely duo -- his meek wife and the mistress he brazenly flaunts. The women become increasingly unhinged by a series of odd occurrences after Delassalle's corpse mysteriously disappears.
