When he is betrayed and killed by his own gang, Guerrero is made an offer he can not refuse by Satan himself. He now has a chance to escape eternal torment in hell, provided that he delivers the souls of his murderers and condemns them to hell in his stead.
In order to protect the world from descending into hell, Guerrero returns to life to protect a stolen relic that could start the end times from falling into the hands of a band of soldiers.
