In the dark days following the Blitz, happiness visits young Pearl Jenkins as she celebrates her marriage to Jim Nesbitt.
But what should be a joyful occasion is marred when a fight breaks out between Jim and Ricky Winters, an unwelcome visitor from Pearl's past. And to Pearl's horror, the new beau of her wayward younger sister Ruby.
Increasingly uneasy at staying at home when other men are off fighting for their country, Jim enlists, leaving Pearl at home - alone, pregnant, and at Ricky's mercy....
Together, Pearl and Ruby must bring up baby Cynthia while struggling to make ends meet and dodge the doodlebugs. And all the time, Pearl must hide the dark secret she harbours, one which would tear the two sisters apart as well as her marriage.
Then tragedy strikes both on the home front and in the trenches and Pearl is forced to fight like never before to keep her family safe.
