Episode one follows a bomb that fell on Martindale Road in the East End of London on the first night of the Blitz. Stan Harris and Norman Pirie were boys in 1940, but their memories of that fateful night are crystal clear.

Episode three follows a bomb that fell on Jellicoe Street in the Scottish town of Clydebank, a tightly-knit community of ship builders and factory workers who worked hard in difficult conditions.
