What happens when a 31-year-old straight woman falls in love with a lesbian? It's 1993, and Gwen Sullivan is agitated. She's been married and divorced and is now living with her scientist boyfriend who loses himself in dark moods. Her job at a tutoring center and her work on the presidential campaign leave her vaguely dissatisfied. She hopes taking a night class in poetry might help. There, the allure of two lesbians takes her by surprise. This prompts her to question who she is-and who she wants to be. Soon she must make one of the most important decisions of her life.
