In 1882, Joseph and Elizabeth Cooley head West to reunite with Elizabeth's family and are stranded in a logging camp just outside Tucson. Then, a wounded Indian stumbles into their camp, and they must defend him against his would-be killer - Doc Holliday. Elizabeth considers Doc a stone-cold killer, but during the course of their tense stand-off, she comes to find that this courtly, ailing man has a surprisingly well-honed sense of justice, frontier-style.
