Nancy Stokes (Emma Thompson), a retired religious education teacher and 55-year-old widow, has spent her entire life in a unfulfilling, routine-bound marriage, having never experienced an orgasm or genuine sexual pleasure. Desperate for adventure, intimacy, and self-discovery, she hires Leo Grande (Daryl McCormack), a charming, thoughtful young sex worker. Over the course of four meetings in a London hotel room, their casual business arrangement evolves into deep, vulnerable conversations that challenge both of their perceptions of intimacy, shame, and self-worth.
