Set near Portsmouth, one of the main bases for the D-Day invasion fleet, the film portrays life on the British home front during World War II. During the run up to D-Day, widowed Martha Dacre (Ursula Jeans) tries to keep house and home together for her two serving daughters and servicemen billeted on her. While her son is away in the Navy, she has chosen to stay at home as a housewife, but when she learns that his ship has been damaged during the landings, she experiences regrets about not taking a more active role in the war.
