October 1940. When VAD nurse Evie narrowly escapes being killed in an air raid during the London Blitz, it propels her to make a life-changing decision to break free of her troubled and unhappy life. She escapes to the Norfolk countryside to start afresh, with a job at the newly opened Great Plumstead Hall hospital, and a wonderful new home at Rookery House. The community of Great Plumstead welcomes evacuees to the village - mothers and children bombed out of their London homes. Sisters Prue and Thea, along with members of The Mother's Day Club, help the new arrivals settle in, while continuing their work for the war effort by holding knitting bees and doing WVS work. But when a patient arrives who knew her in her former life, Evie's newfound freedom and happiness are in danger. Will the secrets of her past be revealed?
