The Searcher 5: Hellfire

Once, John Stone had everything a man could ever want: wealth, position, and a woman who loved him. But that was before the Civil War. Now he's lost his fortune, and his fiancée has disappeared. All he has left is his Colt, a picture of Marie, and a mission—to roam the west until he finds the woman he loves. After a near-fatal attack by a band of outlaws led by an old friend of his, John Stone is brought back to the outlaws' hideout, where Sally Drake nurses him back to health, while her jealous boyfriend decides Stone doesn't deserve the chance to recover.
