Synopsis

An independent, single mother who owns a small hotel on an idyllic Greek island, Donna (Streep) is about to let go of Sophie (Amanda Seyfried), the spirited daughter she’s raised alone. For Sophie’s wedding, Donna has invited her two lifelong best girlfriends—practical and no-nonsense Rosie (Julie Walters) and wealthy, multi-divorcee Tanya (Christine Baranski)—from her one-time backing band, Donna and the Dynamos. But Sophie has secretly invited three guests of her own.
