Kilkenny, 1939. Kitty Flinn is only seventeen when she is forced to give up her newborn to a mother and baby home. Heartbroken and desperate for a fresh start she leaves Ireland behind for London, vowing to never look back.
Years go by and Kitty has a new life in England, but when her communist brother Anthony is injured during the war and ends up in hiding from the authorities, she has no choice but to return home. Food and medicine are hard to come by, so when she lands a nursing job at a hospital in Naas it seems the answer to all their problems. But things become more complicated when her ability to read German is noticed by an ambitious Irish official, Sam Daley...
Sam will stop at nothing to exploit Kitty's translation skills to gather intel from German prisoners, even resorting to digging into her past to ensure her loyalty. Kitty doesn't want to play any part in the war, especially when she finds out it could put Anthony's life at risk. But when Sam offers Kitty a one-time chance of finding her baby in exchange for her help, will she choose her past or her future?
