The lack of Hollywood-style production values forces the viewer to focus on the men and their plight. They unite over their shared desire to escape. Normally civilization prescribes that a criminal must be punished and serve their sentence. Morally that's justifiable. But these men don't come off as hardened criminals. They're polite, well mannered, and trustworthy. The responsibility of society to punish these men is never an issue. We want them to break out and that's a testament to how seemingly honorable these men are. The camaraderie of these five men illustrates a close friendship in which Manu, Geo, Roland, and "Monsignor"" must befriend and rely on each other, as well as Claude Gaspard, the outsider. There's a searing humanity that plays out in their shared plan. In this way, there's a temperament to the men that's not readily apparent but slow builds over the course of the story. Loyalty is their most prized virtue and their devotion is quietly profound.
