In the midst of boisterous and chaotic frontier pre-celebrations, Caleb Marlowereluctantly deputized for the coming eventlearns that local power broker Judge Horace Patterson is targeted for assassination by agents of a financial magnate. Caleb's efforts to thwart the plan, however, are complicated when a ghost from his past shows up with the intention of blackmailing him.

Caleb is commissioned to bring Starr in to face justice after the assassination attempt, but he has his own burning agenda. Starr is his own father, the man who abused and murdered Caleb's mother. Caleb swears his mother's death will be avenged and justice will prevail...or he'll die trying.
It's 1872 and the Katy Railroad is hell-bent on laying the first set of tracks through Indian Territory, but things have stalled out at Ironhead Station. It's a man-a-day, end-of-the-tracks boom camp, meant to live loud and die young. The railroad has hired a new chief of police, a man named Morgan Clyde, but the gambling crowd is giving three-to-one that he'll be dead by the end of the week. If Clyde can't out-think the smart ones, out-lie the sneaky ones, and outshoot the deadly ones, he'll buy himself a one-way ticket to Boot Hill. But he intends to see the smoke wagon rolling once again.
