Wrath of the Crows (2013) on Netflix

Plot summary

A cramped, filthy prison holds inmates who must submit to the cruelty of the head of the guards and his men. Over them all stands the Judge, a man no one has ever seen, and the rules he sets are obeyed by prisoners and guards alike, who fear him. Everyone inside the walls knows the rules they have to keep, yet none of them remembers the life they had before; all that stays with them is the evil they did to end up there. A new prisoner then joins them, Princess, a beautiful woman whose only covering is a fur coat of raven feathers.
