THE ENGLISH CHANNEL. JUNE 1944. On a dark night at the height of World War Two, thousands of ships charge across the ocean towards the French coast. This is Operation Neptune: the beginning of the fight to free Europe from the Nazis. The next few weeks will turn the tide of the war. On board one of the hospital ships, disguised as a nurse, is Martha Gellhorn. A seasoned war correspondent, she talked her way onboard, hiding in a lavatory until it was too late to send her back. Now Martha is on her way to make history as the only woman to set foot on the beaches on D-Day.
