Davide, a boy from a respectable family with a child’s eyes and a grown man’s body, is kidnapped one night and locked in darkness in the back of a truck.

Held captive by a mysterious organisation, he is forced to fight bare-handed in brutal underground bouts that can end only with the death of one of the two opponents.

In this alien and merciless world, Davide must abandon his humanity in order to survive, following the orders of Minuto, who serves as both jailer and trainer to men who have neither hope nor a future.

Gradually, a secret bond develops between the boy and the man, offering Davide his only chance of salvation.

But while it may be possible to escape from prison, there is no escaping fate, or the consequences of one’s actions.
