Back on the time when Vren was seventeen years old, he was a victim of murder. Together with her beloved girlfriend, Gretta. Such a torture in his mind that he cannot do anything to save her from being raped to death. He lived, a second chance of living when he accepted the devil's offer, for him to take his vengeance for Gretta's death. After eleven years, alongside with Zauron, the devil who gave him such power and skills, they both kill many people that for them are living sinners and suspects for Gretta's death. As they chase different kinds of criminals, unlawfuls, and sinners, Vren did not expected to meet various persons that is as same as what he is.
