The Old West had no shortage of gun-toting outlaws willing to use violence to solve their problems. But when it comes to unbridled homicidal mayhem, none quite match John Wesley Hardin. Drifting along with the great cattle drives between Texas and Kansas, Hardin quickly became famous - and feared - for his readiness to settle quarrels with his gun. By his early 20s, Hardin had killed dozens of men, most with a single shot to the head or heart. When his hair-trigger temper leads to the murder of a sheriff's deputy, Hardin is forced out of his native Texas,and left trying to stay one step ahead of the biggest manhunt the U.S. had ever seen.
