Middle-aged businesswoman Paula Tessier resists the advances of Philip Van der Besh, the 24-year-old son of one of her clients. But when her longtime paramour, Roger Demarest, begins yet another casual affair with a younger woman, Paula decides that two can play that game. However, it seems that society looks differently at May-December romances when the woman is the older partner.
