100 Rifles (1969)

Yaqui Joe (Burt Reynolds) is an Indian who robs a bank in order to buy guns for his people, who are being savagely repressed by the government. Set in turn-of-the-century Mexico, it tells the story of his flight into Mexico and his pursuit by an American lawman. They eventually become allies and team up with Sarita (Raquel Welch) to take up the cause of the Indians.
