Fred C. Dobbs and Bob Curtin, both down on their luck in Tampico, Mexico in 1925, meet up with a grizzled prospector named Howard and decide to join with him in search of gold in the wilds of central Mexico. Through enormous difficulties, they eventually succeed in finding gold, but bandits, the elements, and most especially greed threaten to turn their success into disaster.

When a wandering mercenary named Hogan rescues a nun called Sister Sara from the unwanted attentions of a band of rogues on the Mexican plains, he has no idea what he has let himself in for. Their chance encounter results in the blowing up of a train and a French garrison, as well as igniting a spark between them that survives a shocking discovery.
