During World War II, British Army Major Peter Garnett assembles a brave team composed of Captain ‘Red’ Gowan, Private ‘Nobby’ Clark, and Raoul de Carnot, a member of the Free French forces. Their mission is highly dangerous and involves collecting vital intelligence about German military presence and operations along the occupied French coast. Their task is to gather information discreetly, knowing that the German forces are heavily fortified and alert, making every move risky.
Their journey begins with a tense crossing of the English Channel in a small dinghy, watched closely by [Sub-Lieutenant Jackson], who observes the operation and expresses no envy for their perilous undertaking. Nobby, who is familiar with the target area since he once lived in Saint Antoine and ran a café with his French wife Lulu, plays a key role in the operation. Their plan involves splitting up after landing—Gowan and Nobby head toward the village, while Raoul and Garnett go to Raoul’s ancestral chateau, a strategic location. Lulu, Nobby’s wife, warmly greets them, adding a personal touch to the tense atmosphere.
In the village, they soon learn that Michele de Carnot, Raoul’s sister, is hesitant about helping them. She is resigned to the occupation, fearing the repercussions of assisting the Allies, and is too frightened to actively support their mission. Meanwhile, they make contact with M. Fayolle, a local businessman who, despite being hated for his collaboration with the Germans, secretly works with the Resistance. Fayolle and his daughter Estelle have already helped hundreds of Allied soldiers escape, and they provide crucial aid, such as special papers that enable the team to move around undetected.
At the German headquarters, Garnett and Gowan work under false pretenses as champagne salesmen, a disguise that is cleverly aided by a personal letter from Joachim von Ribbentrop and champagne supplied by Nobby. This ruse allows them to gain access and gather intelligence, including photographs of a troop movement map. Their wit and courage enable them to gather more information from unsuspecting German officers, who suspect them to be spies or counterespionage agents. Their activities quickly draw suspicion from [General von Reichman], who contacts Berlin about the intrusion, escalating the danger they face.
One of their most significant discoveries is a secret airfield built into a cliffside, cleverly hidden from aerial bombing. However, their presence is eventually detected by patrolling German soldiers, and Raoul is shot in the woods during a patrol. His death at home, with Michele and the priest at his side, marks a heartbreaking turning point. Michele, grief-stricken and angry, refuses to reveal the rendezvous point Raoul intended to show them—an ancient tree where he and Michele had played as children—so they must return to ask her directly.
The team faces further danger when Fayolle and Estelle reveal their true roles in the Resistance, risking their lives to share vital intelligence. Michele, realizing the threat of a German manhunt now that the Germans have learned of their mission, tries to warn them. She attempts to show the team the tree, but they are captured during a patrol. At the rendezvous point, Private Clark hijacks an armored propaganda truck called the “Music Box,” and with Garnett, they change into Nazi uniforms to blend in. Their plan involves accessing the Nazi headquarters to free Captain Mackenzie, whom they manage to release after Garnett, posing as a German officer, gives orders.
Just before dawn, at 3:15 a.m., the team executes a daring attack by signaling planes to drop paratroopers who land on the factory and blow it up, crippling German operations in the area. After the successful raid, the agents converge at the beach for a final escape. During this emotional moment, Michele and Garnett share a deepening connection. As the others prepare to return to England by boat, Michele declines Garnett’s offer to accompany her, choosing instead to remain in France and continue working with the Resistance. She gives him a small cross for luck and they share a heartfelt farewell, exchanging a promise with their final words: >“Goodbye Michele.” “Au revoir, Peter.”
As Michele walks away with confidence and purpose, the mission’s success and the personal sacrifices made highlight the bravery and resilience of those involved in this dangerous and vital operation.
