In a routine sex farce, Gautier (Jean-Claude Dauphin) is a man determined to figure out how to give a woman an orgasm -- which of course requires a lot of practice and experimentation. His buddy Roussel (Jean-Luc Bideau) also chases after women but does not share Gautier's unique quest. Rose (Nathalie Nell) finds Gautier entrancing and devises a way to capture his heart while helping him on his search for the ultimate turn-on.

Salomé Lerner just finished writing an autobiography. She goes to a TV show called "Apostrophes", hosted by French TV showman Bernard Pivot. Pivot then imagines a film that could be created from her gripping story. A film entirely made of music because after seeing the young pianist Erik Berchot, Salomé believes seeing her long lost brother, who was a musician as well. A brother she had lost along with her parents in 1943. However, the Lerners did in fact escape the gestapo and might have based themselves in Paris...

Set against the backdrop of an increasingly violent strike, a worker falls in love with the middle-class daughter of his landlady.

Doctor Valois has invented the "flashage", a cure for depressed people. After having tested it on monkeys, he tries with a first human patient, Alain Durieux. This is great success, everybody's happy except may be Alain's wife, Jeanne, who's worrying about the changes in Alain's personality. Other patients use the treatment with similar successes, and Valois's happy about it. But the monkeys are changing: non-cured ones are made mad by the over-stability and stereotyped behaviour of the cured ones. So are the humans. When Valois realises he can't stop the process, he decides to "flash" himself.

The series follows the adventures of lighthearted Jean-Paul Moulin, a police Commissaire, and his team as they solve crimes.
