At the close of the Second World War, Intelligence Officer Gus Clifton returns to London. On his arm is Krista, the German wife he married secretly in Berlin. For his two sisters, this broken woman is nothing more than the enemy. For Nella, Gus's loyal fiancee, it is a terrible betrayal. As the three women wonder what hold Krista has over decent, honourable Gus, they begin to ask themselves: How far will they have to go to permanently get her out of their home, their future, their England?
