1873, Absolution, Arizona. A stranger with no memory of his past stumbles into the hard desert town. The only hint to his history is a mysterious shackle that encircles one wrist. What he discovers is that the people of Absolution don't welcome strangers, and nobody makes a move on its streets unless ordered to do so by the iron-fisted Colonel Dolarhyde. The desolate city is attacked by marauders from the sky. As this gunslinger slowly starts to remember who he is and where he's been, he realizes he became the city’s only hope for salvation.
