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.

Cruchot's police office moves into a new building. They do not only get high tech equipment, but also four young female police officers to educate. All of them scramble to work with them -- and cause pure chaos while being distracted by the fine ladies. Then they get into real trouble when one after the other of their female colleagues is kidnapped.

The bungling inspector Cruchot finds himself trying to save the residents of St. Tropez from some oil-drinking humanoid aliens. The only way to tell the aliens from the real people, besides their constant thirst for oil-products, is that they sound like empty garbage cans when you touch them. Chaos is ahead.
