The life of 18-year-old Davide is ruined forever: he is kidnapped, locked inside a truck and forced to fight a stranger until he kills him with his bare hands. He enters then the world of illegal fighting, becoming a ruthless fighter capable of killing any opponent. His captor Minuto becomes his mentor, coach and father. But why was he chosen? Maybe Davide has some guilt to atone for, maybe Minuto has a revenge to fulfill. Eventually Davide will manage to run away from that prison and that endless cycle of violence. He will try and start a new life. He even meets a girl he falls in love with. Perhaps a way out of that nightmare really exists, but he is wrong: from blood cannot come love.
