Rafe Barr, master tracker, spy, and war hero, is locked away in Yuma Territorial Prison for life, wrongly convicted of the murder of his wife and son. Five years into his sentence, Warden Talbot Timmons, who has made Barr's time at Yuma a living hell, offers him a deal; full pardon in exchange for rescuing the young dauther of California's Governor Pendleton from Deadwood's top bad man, Al Swearengen. Rafe smells a rat, but agrees...and finds a whole lot of trouble.
