It is autumn 1944, and Allied armies are driving through France toward Germany. A British Lockheed Hudson is damaged in aerial combat with a German Messerschmitt, and both aircraft ditch in the North Sea about twenty miles off the Dutch coast. The four crew survive, but they cannot send a full mayday; a fragment of their signal does reach England. Among the survivors is Air Commodore Waltby, who carries a briefcase containing top-secret German plans for a successor to the V1 and V2.
Flight Sergeant Mackay rises to the occasion, taking a leading role in the rescue dinghy. He works to keep everyone from sliding over the side, even sharing his boots with the pilot to blunt the cold as night closes in and the sea grows merciless. The group clings to each other, one improvised unit against the ocean, as waves rise and their situation becomes increasingly desperate.
As the weather worsens and a freezing night descends, aircraft suspend the search. The now waterlogged dinghy must endure the cold and the uncertainty, while Waltby’s quiet, grim orders weigh on the group: if he dies, they must get the briefcase to London; if capture seems imminent, they should throw it overboard rather than let it fall into enemy hands.
An RAF Air Sea Rescue launch, known on radios as “Sixty One” and designated Launch 2561, joins the chase. It is commanded by Flying Officer Treherne, with second in command Flight Sergeant Slingsby guiding the crew through mounting challenges—from stubborn weather to mechanical hiccups and a stubborn galley fire. The crew’s resolve is tested as they press toward the drifting dinghy, driven by duty and the slim thread of luck.
On the second day, updated intelligence arrives from the rescued downed German pilot, a crucial turn of information that points the dinghy’s likely location closer to shore than expected. This new lead shifts the search inshore, under the watch of hostile shore batteries and a wary minefield. The tension intensifies as the rescue team threads a dangerous path through hostile fire and navigational peril to close in on the survivors.
Despite the odds, Launch 2561 closes in and delivers the dinghy’s occupants and the precious briefcase back to England. The mission is a hard-won triumph, and the two men who bore the brunt—the injured Treherne and Mackay—are publicly acknowledged and applauded by senior officers for their courage, leadership, and unwavering commitment to duty under extreme conditions.
