Papillon

Henri "Papillon" Charrière, a safecracker from the Parisian underworld, is framed for murder. Though he has an alibi from his lover, Nenette, Papillon is convicted and condemned to the notorious penal colony in French Guiana — a hellish prison from which nobody has escaped.

On the ship to South America, Papillon meets a quirky counterfeiter named Louis Dega. That evening Dega is awakened as two convicts murder a prisoner sleeping next to him in order to cut open his stomach and steal the money he had swallowed. Papillon forms an unlikely alliance with Dega, who is targeted by the other prisoners who suspect him of also hiding money. Papillon saves Dega's life and is punished for fighting by the guards. In exchange for Papillon's protection, Dega agrees to finance Papillon's escape, ultimately resulting in a bond of lasting friendship.
