Outlaws Butch Cassidy and the Sundance Kid have turned a new leaf since their return from Bolivia. Their train robbing days are behind them. Life is settled and good. But when a journal surfaces that links railroad baron E. H. Harriman with the assassination of President Lincoln, all the power of the Union Pacific Railroad is turned with a vengeance on Butch and Sundance. No measure is too extreme to retrieve the journal. The action moves across the country from 1911 New York City, to the mountain town of Crested Butte, Colorado, with colorful characters and danger at every stop along the way.
