The Summer House

Margaret (Lena Headey) has agreed to marry Syl (David Threlfall) ; the problem is, she accepted the proposal to please her aging mother, Monica (Julie Walters), and secretly has no interest in her listless fiancé. As the wedding date draws nearer, friends and family of the bride-to-be begin to arrive, including the free-spirited Lili (Jeanne Moreau), an old friend of Monica's. Luckily, Lili quickly realizes that Margaret and Syl don't gel, and comes up with a brilliant plan to stop the wedding.
