ROXY'S search for her father, bounty hunter Gavin Doyle, has been fruitless. She finds herself in Sheridan, Wyoming, after following a rumor that he was there. While in town a woman named Jane Doyle approaches her claiming to be Gavin's wife. She tells Roxy her father's in trouble and needs help, and that she'll lead her to him. Roxy prepares to leave Sheridan on horseback with Jane, but the following morning the woman has vanished. Roxy is determined to track her, no matter how far, to find if she was telling the truth about being married to Gavin Doyle. But, whether or not the woman's husband is her father, Roxy discovers they are being tracked by a band of outlaws, intent on killing them. Roxy must do what she can to keep everyone alive, including herself.
