Leslie Caron (Gigi) was Oscar-nominated for her portrayal of Jane, a young pregnant French girl who moves to a seedy boarding house in London for a new start. Beautiful and withdrawn, Jane slowly gets to know the other residents of the house who, like her, are social outsiders in their own way. As she falls into a relationship with Toby (Tom Bell) a struggling young writer who lives on the first floor, and befriends Johnny (Brock Peters) a black jazz musician, Jane finds a new reason to five. She considers getting an abortion, but is unhappy with this solution. Eventually she comes to like her odd L-Shaped room, but still faces two problems: what to do with her baby, and what to do with Toby.
