When Galen Benitez killed Mike Donohue's wife, Mike vowed to get his revenge that very day. But it took five long years before he tracked the outlaw down to the inhospitable region known as the Cauldron.

Here, Mike meets the beguiling Lucy Reynolds who is searching for the legendary lost city of Entoro, a place rumored to have its streets paved with gold. As Mike suspects that Galen might also be searching for the treasure, he decides to help her.

With Galen still at large, and now Lucy's jealous admirer determined to kill him, Mike will need his trusty six-shooter to ensure that he isn't the one who is dead by sundown.
