EastEnders actress June Brown relives her wartime experience in the Wrens, when women were encouraged to join the war effort to 'free a man for the fleet', and takes the controls of a warship as she finds out what life is like for women serving in the Royal Navy today. As she recalls her own work as a cinema operator showing training videos to troops, and gets a taste of the opportunities available today, June finds her own views on women's roles in the forces challenged, leading to a surprising change of heart. June also meets a veteran of the D-Day landings and sees a dramatic training exercise, as recruits are taught how to tackle a blaze aboard a ship.
