Les petites garces.

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.
