 Matt, in pursuit of three bank robbers, inadvertently catches a fourth one -- their bagman, who swiped the loot and took off. The thieves learn what s happened and go in pursuit of both Matt and the thief. While stopped at a water hole, Matt and the thief meet a group of Indians who are about to leave a squaw in the desert to die. The startled thief asks why and is told the woman is a bad-luck omen, having outlived both of her husbands. To his own surprise, the thief bargains to take the squaw with him and Matt. He doesn t have any regard for the woman, but she proves startlingly helpful when the bank robbers catch up with the group and lay siege to their cabin.
