N/A - Riches et garces - 1979

The twin sisters are played by the real-life American twins Denise and Diane Sloan.
Monsieur Mendel, a rich businessman, has retired to Italy where he enjoys sailing. His secretary “takes care” of him so well that one day he has a heart attack. Learning that he doesn’t have a long time to live, he asks Paul, his associate, to find the three daughters he has had. Paul finds the first one (Isabelle) in a sexy party in Paris. Then he finds Angelia who is a nurse in a convent in Calabra. A contact in New-York finds the third one (in fact twin sisters) who are prostitutes of some sort. Despite the hatred they all feel for their father, they agree on seeing him on his boat. Mendel tells them that the one who gets married for love will inherit his fortune.
An Italian gigolo immediately sets himself on the twin sisters and Paul feels attracted towards Isabelle. Things are not so good for Angelia who is raped by the gardener of the convent.
When the daughters intoduce their would-be husbands, M. Mendel tells them the truth: he is totally penniless. The gigolo vanishes and Angelia goes back to her convent. Paul and Isabelle fall into each other’s arms. And all ends well.
