It is 1944, and the Adams family, along with the rest of the people of the United Kingdom, are beginning to weary of the seemingly never-ending war against Hitler’s Germany. Bobby Somers and Helene, living dangerously in the French countryside with a group of Resistance fighters, find themselves in great peril. Boots returns from the war in Italy, to the delight of Polly and their two little rascals, twins James and Gemma - but he brings with him a German prisoner who has a horrifying story to tell of the concentration camps. And while Sammy and Susie Adams are keeping the family business going as best they can during the privations of wartime London, their son Daniel catches the eye of a lively young American girl who brings a welcome breath of fresh air to the Adams household, so many of whose younger members are doing their bit for the war in various far-flung places of the world. As plans for the long-awaited invasion of France get under way there is excitement and danger, but love continues to blossom in the most difficult of circumstances.
