Cowboys & aliens.

Summary/Review: The Old West.. where a lone cowboy leads an uprising against a terror from beyond our world. 1873. Arizona Territory. A stranger with no memory of his past stumbles into the hard desert town of Absolution. 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. It's a town that lives in fear.
