Michelle De Winter lives the good life, wining and dining with only the richest men who are fortunate to cross her path. Her daughter Yvette, whom Michelle insists on introducing as her 'niece', is a fashion model. She is saving herself for the right man, despite the fact that she is part of the free love generation and lives with a group of promiscuous creative types. While Michelle is searching for a new millionaire playboy, Yvette falls for the handsome Peter Von Hallstein. She asks the fatherly Dr. Fink to help her come up with a scheme to get Peter to propose to her.
