Middle-aged businesswoman Paula Tessier rejects the advances of her client's amusing 25-year-old son, Philip Van der Besh, but reconsiders when her longtime philandering partner begins yet another casual affair with a younger woman. She soon learns that May-December romances with older women are frowned upon in society.
