Despite being trapped in an abusive marriage, Maggie still feels blessed with her eight-year-old twins, Danny and Lizzie, and baby girl, Lucy. But when the Second World War begins it seems that herblessings may have run out. Although the war lets her escape her husband when he's sent to the front, she must also lose the twins, as they're evacuated to North Wales. Lizzie seems to be in the perfect family, while Danny is left with a man who seems to resent his presence. But appearances can be deceptive, and while Maggie struggles to survive the bombings at home, her children face danger of a different kind.
