But outside of the factory things are more complicated. Lily Renee's older sister has returned home after six years and is hiding a secret. Meanwhile Esther is finding life in England more difficult than expected and it's not long before Renee is in trouble with nowhere to turn. In the face of the Blitz the Yardley girls are bound together by friendship - but are the secrets they're hiding the biggest danger of all?
