It is late August 1940 & British Intelligence agent Hope Stapleford is desperate to join the Special Operations Executive. But spymaster Fitzroy, now Hope’s stepfather, has promised to protect her, so instead he sends her to work in the home propaganda department of the Ministry of Information. When bombs start to fall in London and lives are tragically lost, Hope secretly becomes an ARP warden and her asset, Harvey, becomes a nightshift fireman on the East End docks. And as the Blitz rages on, Hope must keep the nation’s spirits up, while never knowing where the next threat to her safety lies.
