A bounty hunter known only as the Stranger pursues and captures an assortment of criminals, trying to scrape together enough money for a mysterious operation. When he hears that a town of Grubbs has been overrun by a demon, the Stranger heads there. The town was once protected by a race called the Steef, now seemingly extinct, and the Stranger soon learns that a nearby river has been dammed and dried up by a figure named Sekto. As he continues hunting outlaws — and revealing nothing of his own past — the Stranger must confront Sekto.
