Вот там действительно жесть.
After defending Dega against a sadistic guard, Papillon is sentenced to solitary confinement. In gratitude, Dega smuggles extra food to Papillon. When the food smuggling is discovered, prison guards cut Papillon's food rations in half with the expectation that hunger will force him to reveal the name of his benefactor. Though emaciated and half-insane, and reduced to eating insects to survive, Papillon refuses to snitch on Dega and is released from solitary confinement after two years, including six months in total darkness and on half rations. Reunited with Dega, they soon begin planning their escape.
