人到中年，愛麗斯重新挖掘身體與情慾的種種可能，擁擠的不只是她的生命，還包括他們的房子：偷腥的老公、三個各有困擾的孩子，還有高堂老母。一個屋簷下藏有多少祕密？洶湧的情感暗流在屋子裡外角力，一如暗影偏斜。獲得多項國際影展肯定，性、愛情與音樂，所叩問的無非是生活的本質：我們苦心維持的究竟是家，或只是房子？

Alice, married for the last 20 years to a taxi driver, works in a beauty parlour, has three children, the eldest of whom is doing his military service, and a mother who works as a maid in her house. None of the three siblings pay much attention to their mother, and they treat their grandmother with lack of respect. Alice's life in the female working world contrasts strongly with the powerful masculine presence in her home. Although she's a good girl, the chance to betray uncovers other betrayals she didn't know existed.

Alice (Carla Ribas) é uma manicure que tem em torno de 40 anos e está com a vida estagnada. Ela mora na periferia da cidade de São Paulo com seu marido e seus três filhos. Ao lado da família, tenta levar a vida do melhor jeito possível ao enfrentar os problemas do dia-a-dia. Alice sabe que o marido encontra outras mulheres, mas releva porque também sai com outros homens.
