When Victor is arrested for a murder that, for once, he didn't commit, escape must surely be inevitable for a hitman of his ferocity.

Yet someone wants Victor put away, and he finds himself behind bars, incarcerated by police who have no idea of the monster they are dealing with and have, apparently, tamed.

Quickly, however, his fellow prisoners realise that he's not trapped in there with them: they are in a cage, with the most dangerous of enemies. And Victor has a traitor to find.
