Butch Cassidy in Sundance Kid sta bandita, ki skupaj načrtujeta in izvajate rope, da bi si tako zagotovila boljši finančni položaj. Eden od takih načrtov je tudi rop na železniški progi, ki pelje tovor na ladjo. A v svojem načrtu spregledata namero železniške družbe, ki takoj za tovornim vlakom pošlje še en vagon, natovorjen s šerifovimi pomočniki. Vendar jima nekako le uspe uiti zasledovalcem. Zbežita v Bolivijo in že kujeta nove junaške načrte za Avstralijo.
Butch and Sundance are the two leaders of the Hole-in-the-Wall Gang. Butch is all ideas, Sundance is all action and skill. The west is becoming civilized and when Butch and Sundance rob a train once too often, a special posse begins trailing them no matter where they run. Over rock, through towns, across rivers, the group is always just behind them. When they finally escape through sheer luck, Butch has another idea, "Let's go to Bolivia". Based on the exploits of the historical characters.
