It's 1945 and the war is finally over. For the Devlin family in Liverpool, the wartime years have been almost too much to bear. But at long last sisters Grace and Chrissie can return to their normal lives. Level-headed and hard-working, Grace wants nothing more than to meet a nice man and settle down. Vivacious Chrissie, though, craves fun and excitement - and there's not much of that to be had in the austere post-war years. So when Chrissie meets Pat Kilroy, a handsome Irishman, she's swept off her feet and eagerly follows Pat to Ireland. Chrissie soon realises she has made a terrible mistake, and Grace rushes to her side to help. But the consequences of Chrissie's actions are to be as far-reaching as they are devastating.
