During the Nazi occupation of France, the Peugeot family found itself running a factory the Germans needed for military vehicles, and used that position to wage a quiet war from the inside. The film traces how factory bosses and workers coordinated with the French Resistance to slow production, damage machine tooling, and misdirect vehicle parts, turning compliance into camouflage for deliberate sabotage. Interviews and archival footage lay out the risks involved: discovery meant deportation or execution, and the film details the close calls and betrayals that came with running a covert operation inside a facility under constant German oversight. It sets the Peugeot story against the wider mechanics of industrial resistance across occupied Europe, where owners and laborers alike had to decide how far to cooperate and where to draw the line. The result is a portrait of resistance measured in bent machine parts and delayed shipments rather than gunfire, a slower and less visible kind of fight against the German war machine.
