In the thick of a midlife crisis, television writer Isaac Davis (Woody Allen) finds himself torn between the sweet but far too young Tracy (Mariel Hemingway, who received an Oscar nod for the role) and his best friend's mistress, Mary (Diane Keaton). Shot in black and white and in wide-screen format -- both firsts for director Allen -- this film is as much a paean to the city he calls home as it is a tale of Davis's romantic foibles.
