Widowed for many years, with grown children, Sarah is a writer who works in the theater in London. During the production of a play, she falls in love with a seductive young actor, the beautiful and androgynous 28-year-old Bill, and then with the more mature 35-year-old director Henry. Finding herself in a state of longing and desire that she had thought was the province of younger women, Sarah is compelled to explore and examine her own personal history of love, from her earliest childhood desires to her most recent obsessions.
