When the Danford Gang terrorized Arizona, no one -- not the U. S. Marshals or the Army -- could bring them in. It took Wild Bill Hickok to do that. Only Wild Bill was able to put them in the Yuma Territorial Prison, where they belonged. But the prison couldn't hold them. The venomous gang escaped and took the Governor's wife and her sister as hostages. So it was up to Wild Bill to track them down and do the impossible -- capture the Danford Gang a second time. Only this time, the gang's ruthless leader, Fargo Danford, had a burning need for revenge against the one man who had put him and the gang in prison in the first place, a need as hot as the scorching Sonora sun ... and as deadly as the desert trap he had set for Bill.
