A Fistful of Dollars (1964)

"In his own way he is, perhaps, the most dangerous man who ever lived!"

The Man With No Name enters the Mexican village of San Miguel in the midst of a power struggle among the three Rojo brothers and sheriff John Baxter. When a regiment of Mexican soldiers bearing gold intended to pay for new weapons is waylaid by the Rojo brothers, the stranger inserts himself into the middle of the long-simmering battle, selling false information to both sides for his own benefit.
