Kate, Sally, Maxine & Elsie work at the naval armament depot on the shores of Portsmouth harbour. The hours are long & the work difficult & dangerous but even in the dark days of World War II they still find time to enjoy themselves, at the ENSA concerts & hops in the local drill hall. However, beneath the careless laughter each girl nurses a secret. Kate is terrified that she carries a jinx, while Maxine has discovered a family secret which turns her bitterly against both her parents. Elsie is still grieving over the loss of her son Graham, killed in the Blitz. & spirited young Sally has lied about her age in order to get her job. Each faces a dilemma that will be resolved only after D-Day in June 1944. What happens then brings each woman face to face with her own strengths & failings &, ultimately, her own destiny.
