XII century. Human rights, humane treatment of prisoners, the highest priority of human life... Everything fits in one place - the scabbard hanging on the winner's belt. Kill or kill you. How to survive in these conditions for someone whose worldview was formed in the second half of the 20th century? Accept the rules of the game and walk on corpses? Do not accept? And being killed or becoming a slave? Try to change something? It still takes strength. And if you are not yet fourteen, but life asks you without discounts, as an adult, and then on the one hand, then on the other hand, death threatens? If friends you could not protect die? Until you gain strength, until generosity - the weapon of the strong - is not for you, become cunning, dexterous and merciless, become Mad Fox.
