Defending this system is idealistic security officer Leo Demidov, a war hero who believes in the iron fist of the law. But when a murderer starts to kill at will and Leo dares to investigate, the State's obedient servant finds himself demoted and exiled. Now, with only his wife at his side, Leo must fight to uncover shocking truths about a killer-and a country where "crime" doesn't exist.
