The vicissitudes of showbiz take the hero Renart (Gerald Battiaz) and his wife Hermeline (Francoise Dupertuis) from up to down and back again in this brief drama. Renart entertains at a nightclub by pulling objects out of a suitcase on stage and creating a wide range of sound effects with his collection of odds and ends. All goes well until his wife is fired from her job at the club because she is pregnant. That infuriates Renart, and he quits. The couple then take off for the mountains and open up a club of their own, but now when he is the owner, Renart is transformed for the worse.

The life of the actress and model Capucine inspired this film by Michel Soutter, played by Capucine herself in the company of Heinz Béat, Antoinette Moya, Corinne Corderey and Jean-Pierre Malo.

Although there are women in the lives of the three main protagonists -- a middle-aged architect, his construction designer, and a journalist -- the women are not as crucial to the men's search for an identity as the title might suggest. When the three men run into a former professor of the architect and designer, they are inspired by his fanfare and expansive nature. Still in search of solutions to their particular problems, the men head out to visit the professor and get to the bottom of their own issues. Unfortunately, the professor turns out to be more "loco" than otherwise, and the three men watch their hopes burst like a popped balloon -- it seems like their ability to assess human character should now be added to their list of problem spots.
