Maggie Hosking is in her early sixties, and she lived in Devon with a husband who never worked and took her for granted. But now Maggie is going to have an adventure of a lifetime taking her to London, New York and Martha's Vineyard. All her working life Maggie has been a cleaner in hotels and private homes. Maggie cleaned for actress Helen Heacham's parents until their deaths, when Helen moved Maggie up to London to take care of her home. Helen lives in a beautiful terrace in Kensington along with famous and not so famous neighbours. Actors, writers, models and businessmen; they all seem to need a cleaner and that's when Maggie's adventure starts.It's not just Maggie's life that's changing but big things are happening for the other residents in the terrace; success, romance and fraud, but most of all friendship.
