As this direct-to-video western opens, a violent dust storm engulfs a potentially lethal stretch of desert. Two enigmatic strangers with mysterious wounds on their backs follow a trail of smoke curling up over the horizon. Meanwhile, hunger, dehydration and exhaustion take their toll, pushing the men ever loser to death. The travelers cross paths with Caleb Williams, a good and decent man still coping with his wife's death; he helps nurse the strangers back to health. Joining forces, the three venture out to a small town on the outskirts of Yuma to aid a desperate preacher in his fight against an overwhelming evil.
