The Firefly of France

Somewhere above the shell-pocked Marne, a lone Sopwith threads a comet-green flare through the moonless dark—an ethereal signature that earns its pilot the sobriquet “Firefly.” When this luminescent guardian fails to limp home, Allied command discovers that the canvas tube strapped to his thigh contains not mere maps but the skeletal blueprints for the spring ’18 counter-offensive; its loss would cauterize every hope of breaking the Hindenburg vice. Rumor swirls that the aviator has been corralled by a Bavarian Jagdstaffel now loitering near Reims, or, worse, has bartered both life and documents to a clandestine ring of Berlin spies who haunt the champagne cellars beneath the city’s basilica. Enter Blaine Rawson—laconic Kansas farm-boy turned Lafayette Escadrille ace—whose Curtiss Jenny still smells of prairie wind. His orders masquerade as a routine patrol; his true mission is to stalk the night sky where the vanished flare last glimmered. Over the scarred earth of Lorraine he tangles with a triplane emblazoned by a crimson harlequin, then crash-lands inside the phantom grounds of Château de Bellecroix, a place locals insist is cursed ever since its chatelaine danced herself to death in 1789. There Rawson meets the château’s present chatelaine—Lisette de Gramont—an enigmatic girl whose velvet choker conceals a locket keyed to the same cipher that encrypts the missing plans. Lisette’s loyalties oscillate like a metronome: she quotes Verlaine to German officers at dusk, yet at dawn slips cognac to wounded poilus. Together they plunge into a labyrinth of subterranean canals once used by Huguenot smugglers, pursued by Oberleutnant Kestner—an aesthete who recites Rilke while tightening the thumbscrews—and his coterie of trench-coated agents who can counterfeit any accent from Brooklyn to Bruges. Each double-agent’s betrayal tightens the film’s moral vice: a monocled signals officer who listens to Debussy on a portable gramophone; a Vicomte who sells vintages to both armies; a Red-Cross nurse whose scalpels flay more than shrapnel. In a climax staged inside the ruined cathedral of Saint-Hilaire, stained-glass saints witness propellers hacked into cruciform shadows, tracer rounds ricocheting off medieval frescoes, and the final revelation that the Firefly is no prisoner but a willing defector whose heart was hollowed out by an earlier war-crime—a secret Lisette carries like shrapnel beneath her collarbone. When the cathedral’s bell—silenced since 1914—tolls once more, the true custodian of the plans is not who espionage etiquette dictates, and the flare that ascends is neither German nor French but something incandescently human.
