Summary: Michael James, a notorious womanizer, desperately wants to be faithful to his fiancée Carole, but runs into serious problems since every woman he meets seems to fall in love with him. His psychoanalist Dr. Fassbender can't help him either since he's busy courting one of his patients who in turn longs for Michael. A catastrophy appears on the horizon as all the characters check into the Chateau Chantelle hotel for the weekend not knowing of each other's presence.
