Resistance cell leader and SNCF area inspector Paul Labiche initially rejects the plan, telling Mlle. Villard and senior Resistance leader Spinet, "I won't waste lives on paintings"; but he has a change of heart after a cantankerous elderly engineer, Papa Boule, is executed for trying to sabotage the train on his own. After that sacrifice, Labiche joins his Resistance teammates Didont and Pesquet, who have been organizing their own plan to stop the train with the help of other SNCF Resistance members. They devise an elaborate ruse to reroute the train, temporarily changing railway station signage to make it appear to the German escort as if they are heading to Germany when they have actually turned back toward Paris. They then arrange a double collision in the small town of Rive-Reine that will block the train without risking the cargo. Labiche, although shot in the leg, escapes on foot with the help of the widowed owner of a Rive-Reine hotel, Christine, while other Resistance members involved in the plot are executed.
