Liverpool, 1940. �_oWhere�_Ts George?�__ Ruth didn�_Tt realise that she had grabbed hold of the other woman�_Ts arms. �_oWhere�_Ts my son?�__ Journalist Ruth Holt is struggling in the terror of the Blitz when her young son is suddenly snatched away in broad daylight. Soon after, the kidnappers�_T demands arrive. They are working with the Nazis, and she has no choice but to co-operate, or the authorities will learn that she is harbouring secrets of her own. Ruth�_Ts job gives her access to critical information, and if she does not share it with Britain�_Ts enemies, her child will face the consequences. Desperate, she falsifies information, lying to everyone: her employers, her family and her lover. But as the demands increase, the knife edge she walks on grows increasingly thin. If she falls, she will never save her son.
