Hucknall 1941. Female conscription looms and three women arrive at the Bell Works Factory to work on the Spitfire production line. Lily soon realises her real dream is to pilot the planes; Edna longs to be reunited with her evacuee daughter but soon discovers she has a much bigger problem; and Jeannie fears the worst after weeks of no news from her friend Frank. Despite all the heartache with a bit of festive cheer and 'can do' attitude the Engine Girls will pull together and do all they can to ensure Britain is safe for the New Year.
