Norfolk, 1940. As war rages on, the residents of Great Plumstead are doing all they can to help the war effort, from running the mobile canteen for the Women's Voluntary Service to organising clothing drives and collecting salvage. When a young German girl seeks refuge at the local hall, many welcome her with open arms, while others treat her with suspicion. But when the government try to send her back, it'll take the whole community to keep her safe from war.
