A man named Brandon had been about to hire Sundance for a mystery job. When he got wind of it, Texas Governor Lester Dukes was determined to find out just what it was. So he called in Yancey Bannerman, with orders to go undercover, and posing as Sundance, blow whatever crooked scheme it was wide-open.Yancey and his gun-swift partner Johnny Cato, met violence at every turn and almost died on the Mexican desert they called the White Hell. But the real shock was still to come ... when Bannerman discovered just who Brandon really was.
