The Governor of Kentucky hires the Pinkerton Agency to get involved in the Hatfield-McCoy Feud. He wants Devil Anse Hatfield, the head of the family, brought to justice. But after two Pinkerton Ops disappear, Robert Pinkerton tells the governor there's only one man he can think of to take on the job now—Clint Adams, the Gunsmith. But Pinkerton knows Clint won't do it if he asks, so he advises the Governor to send the Gunsmith a telegram and pique his interest. Pinkerton knows that Clint will respond out of pure curiosity. Once he does he rides into West Virginia and becomes embroiled in the deadliest feud in history.
