In 1899
Wyoming,
Butch Cassidy is the affable, clever, talkative leader of the outlaw
Hole-in-the-Wall Gang. His closest companion is the laconic
dead-shot "
Sundance Kid". Irritated by Cassidy's long absences, the gang selects
Harvey Logan as their new leader. Cassidy defeats Logan in a
knife fight to retain the gang's leadership and uses Logan's idea to rob a
Union Pacific train on both its eastward and westward runs, agreeing that the second robbery would be unexpected and thus reap more money than the first. The first robbery is a success and Cassidy visits a favorite
brothel to celebrate. The town marshal appeals to the townsfolk to organize a
posse to track down the gang but his speech is hijacked by a friendly bicycle salesman. Sundance visits his lover, schoolteacher
Etta Place and Cassidy joins them, taking Place for a ride on his new bike. During the second robbery, Cassidy uses too much
dynamite on the
safe and demolishes the baggage car. As the gang scrambles to gather the scattered money, a second train arrives carrying a six-man team of lawmen. The crack squad pursues Cassidy and Sundance, who hide in the brothel but are found and have to make a getaway. Cassidy and Sundance elude their pursuers by jumping from a cliff into a river far below. Place tells them the posse has been paid by Union Pacific head
E. H. Harriman to remain on their trail until they are both killed. The trio escape to
Bolivia, which Cassidy envisions as a robber's paradise. Sundance is contemptuous of the country and its living conditions. Place teaches them enough
Spanish to pull off a bank robbery and they become successful bank robbers known as . Their confidence drops after seeing a man wearing a white skimmer, fearing Harriman's posse is still after them. Cassidy suggests "going straight," and they gain honest work as
payroll guards for a mining company. They're ambushed by local
bandits on their first run, and their boss, Percy Garris, is killed. They kill the bandits, the first time Cassidy has ever shot someone. The duo concludes the straight life is not for them. Sensing they will be killed should they return to robbery, Place returns to the United States. Cassidy and Sundance steal a payroll and the
burro used to carry it. A boy in a small town recognizes the burro's
brand and alerts the police, leading to a gunfight with the outlaws. Cassidy and Sundance are wounded and take cover inside a building, unaware the local police have been reinforced by
Bolivian Army troops. The pair charges out of the building, guns blazing, into a hail of bullets. The film ends with the sound of gunfire on a
freeze-frame shot of the two running bandits. ==Cast==
