Michel Montfort

Five girls spend their holidays in an old mansion in the middle of a farm in southern France, near Soledor. The lady of the house has a secret that the five wild girls will try to discover. They assume it is a hidden treasure somewhere, but it is only a way to hide a dramatic fact that concerns one of the girls.

A jewel thief crosses paths with a woman carrying a briefcase that the Americans, the Russians and the Chinese all want desperately, so he goes on the run with her figuring that what's inside the case has to be way more valuable than anything he could steal on his own.
