In Bolivia, Butch Cassidy (now calling himself James Blackthorn) pines for one last sight of home, an adventure that aligns him with a young robber and makes the duo a target for gangs and lawmen alike. The film follows 20-year-old Butch Cassidy as he returns to the United States after learning of the death of Etta Place, setting off on a perilous journey across the desert plateau in search of a way out.
