Night Diving is both a young woman's coming-out story and a 30-something coming-of-age journey that proves you can go home again. It is the story of Rose Salino, a thirty-year-old woman living the San Francisco chic lesbian lifestyle, who loses her job as a chef and her lover on the same day. The next day her grandmother dies and in the course of returning to her hometown for a funeral, she sees her childhood best friend and first love, Jessie. They begin to rekindle their friendship, which later becomes a romance. Through a series of crises Rose is forced to look at her life and find the courage to create a future that is true to her real self and her heart.

With the support of friends and the hard lessons born from life's challenges, Rose takes the risks to create a life she wants rather than the life she thinks she's "supposed to have."
