Novaia Zemlia

I suggest that everyone see Novaia Zemlia. Even if you don't understand the dialog, which I didn't, you really should download it. It is a b-film prison drama smart enough to know that its masquerade as an earnest look into step-by-step behind bars dehumanization is just an excuse for axe fights without armor and on-screen people-eating is just that, a masquerade.
The plot is like this: a group of Russian prisoners is secretly sent by the UN to colonize an Arctic island, and when they land with hands still in shackles they are provided with just enough food, water and tools (i.e., axes) to last them three months. In addition, numbered keys matching the prisoners' handcuff numbers are left in a heap on the beach; the prisoners precipitate towards the keys, and the first ones to find their match rush back to the crates full of axes and begin slaughtering the ones still in shackles. One of the prisoners just walks off, deciding to subsist alone in the woods rather than subsist among degenerates.
He is soon joined by another prison, but after trying to live off sea slime in the dead of winter, they come crawling back to the prison colony together and wind up falling asleep in a heap of still-warm ashes. One of them is awakened by prisoners carrying a dead guy on a spit towards the fire, but the two get caught and dragged back to camp.
They discover that the prisoners, instead of creating a new society on the island, had simply continued living in prison fashion, right down to the inflatable sex dolls. The prisoners create an institution to resolve their food shortage: the rank and file live crammed together in a barracks, and during the afternoon walk, a lackey announces that the last one inside the barracks gets eaten.
