Inspired by Buth Cassidy and the Sundance Kid, Simon Casson and Richard Adamson set out on horseback to retrace the real-life footsteps of their boyhood heroes, covering 2,000 miles of the country's toughest and most treacherous terrain. Together they grapple with hostile landscape, climatic extremes, vital supply shortages, and enormous personality clashes. Battling from one outlaw hideout to another and following trails sometimes only accessible by horseback, they are constantly taxed to the limit. In this dramatic account of their adventure, Simon and Richard also encapsulate the exciting and violent lives of the Wild Bunch 100 years ago, and provide an intimate and heartwarming picture of the rancher families who live and work this demanding land today.
