The Treasure of the Sierra Madre (1948)

Two down-on-their-luck Americans searching for work in 1920s Mexico convince an old prospector to help them mine for gold in the Sierra Madre Mountains. They find land on which much gold can be mined, and they split the gold equally, but greed and mistrust threaten to tear them apart. As they face bandits, desert journeys, and the loss of their fortune, they learn the true value of friendship and resilience.
