A university professor (Gena Rowlands) experiences a midlife crisis, so she rents an apartment next to a psychiatrist's office in order to write a book. There, she inadvertently eavesdrops on what transpires between the doctor and some of her patients. Soon, she becomes obsessed with the life and ongoing therapy of a woman who believes that her marriage is ending. Woody Allen directs this psychological drama co-starring Gene Hackman and Mia Farrow.
