D-Day the Sixth of June

A joint American-British-Canadian commando unit, Special Force Six, is dispatched to destroy a heavily defended German coastal gun emplacement on the Normandy coast. With D-Day looming, the ship carries the operation and the men toward the target. Onboard, the two commanding officers silently reflect on their love for the same woman, foreshadowing personal tension beneath a professional mission.

Captain Brad Parker, an American paratrooper invalided by a broken leg, is posted to the European Theatre HQ in London. At the Red Cross club he meets Valerie Russell and, despite being married, falls in love with her. Valerie is the daughter of a crusty brigadier who has been on sick leave since being wounded at Dunkirk.

Valerie is also in love with Lieutenant Colonel John Wynter, a friend of her father. The two men become rivals in love as their professional paths cross with Parker's growing feelings. The love triangle adds personal tension to the unfolding story.

Both Parker and Wynter are posted overseas, and Parker volunteers to join what becomes Special Force Six, to be led by his former commander, Timmer. The unit gathers seasoned veterans under a looming high-stakes mission. The personal connections across the ranks raise the stakes beyond pure military risk.

With only a few hours before embarkation, Timmer goes to pieces and is arrested for drunkenly breaking security. The crisis exposes cracks in command at the last moment. The looming operation now hangs on whether a replacement can stabilize leadership.

Lt. Colonel John Wynter, having recovered from earlier wounds, is brought in to command the operation. He accepts the burden and seeks to steady the unit under pressure. His appointment marks a pivotal shift in the mission's leadership.

The operation proceeds under Wynter's leadership as Special Force Six breaches defenses and presses inland toward the coastal emplacement. The mission aims to neutralize the gun and pave the way for the wider invasion. Casualties begin to mount as the fighting intensifies.

Captain Parker is badly wounded during the fight and evacuated from the front line to a hospital facility. His injury interrupts his personal involvement in the mission and foreshadows the end of his romantic arc. The evacuation also underscores the high human cost of the operation.

Wynter is wounded in the action and, while awaiting evacuation, steps on a mine and is killed. His death marks a sobering concession of the cost of leadership in war. The loss compounds the emotional stakes tied to Valerie's complicated loyalties.

In a hospital awaiting repatriation, Parker sees Valerie for the last time. She keeps quiet about Wynter's death and they share a final embrace before parting. The moment seals a personal tragedy amid a larger battlefield victory.

Valerie leaves the hospital with her head hung in despondent loneliness. She bears the weight of Wynter's death and Parker's ongoing fate, while the triangle remains unresolved. The scene closes the romantic subplot on a somber note as the men return to their separate duties.
