Plot
A few hours before D-Day, Special Force Six, a joint American-British-Canadian commando unit, embarks to destroy an especially well-defended German coastal gun emplacement on the Normandy coast. As the landing ship steams towards it, its commander, an Englishman, and one of his subordinates, an American, reflect on their love for the same woman.
Captain Brad Parker, an American paratrooper invalided out because of a broken leg suffered during a parachute jump, is posted to the headquarters of the European Theatre of Operations in London. At the Red Cross club, he meets and, despite being married, falls in love with Valerie Russell, an Auxiliary Territorial Service subaltern. Valerie is the daughter of a crusty brigadier who's been on sick leave since being wounded at Dunkirk. Valerie is also already in love with Lieutenant Colonel John Wynter of the British Commandos, a friend of her father.
Both officers are posted overseas, but later return. Parker has volunteered to join what becomes Special Force Six, to be led by his former commander, Lt. Colonel (now full Colonel) Timmer.
