1940. World War Two is sweeping across Europe and the Guernsey evacuee families have just arrived in Stockport. Desperately in need of kindness, love and a safe place to call home, local trainee nurses Clare and Gaye immediately volunteer, alongside their new friend Diana. While the rest of Britain is under siege, Clare is learning how to be a great nurse under pressure, Diana has found that love can be found in unexpected places and Gaye is hiding a terrible secret. But as the reality of war comes closer, all three girls will face personal challenges or tragedies as life changes in ways they could never have imagined.
