Isaac, 42, has divorced Jill. She is now living with another woman, Connie, and is writing a book in which she will reveal some very private points of their relationship. Isaac has a love affair with Tracy, 17, when he meets Mary, the mistress of his best friend Yale. Yale is already married to Emily. This ever delightful movie stars Woody Allen as Isaac Davis, Diane Keaton as Mary Wilkie, Michael Murphy as Yale and Mariel Hemingway as Tracy. One of my favorite Woody Allen... and there are many!
