Six ferocious outlaws that brought chaos and terror in Arizona towards the end of 1800. Initially hired by the white people to exterminate the Apaches, they even went after those who have summoned them. The Krieger Gang was eventually ambushed and terminated by a group of Apaches in 1880. More than a century later, their spirits came back, in the bodies of a group of actors who used to impersonate them and started to ravage again as immortal zombies.
