Roger is in trouble, but he will bounce back. All he had to do was obtain a modest loan from Monsieur Durieu, a banker's son. But Durieu refuses him his money. Humiliated, Roger decides to take action: he kidnaps Durieu and handcuffs him in an abandoned barn. Monsieur Durieu then offers him a deal: break into the safe room of the bank of his sworn enemy. The two men fraternize around their new common cause, the one that could finally make them Great Lords.
