A Fistful of Dollars (1964)

With nothing but profit on his mind, a taciturn American with a lightning-fast right hand rides into San Miguel, a sun-bleached border town where everyone is either rich or dead. As the amoral man with no name discovers that the sleepy town provides the perfect opportunity to make a quick buck, the mysterious stranger soon finds himself caught in the middle of a destructive, long-standing feud. After all, the corrupt Baxters and the murderous Rojos, two feuding families fighting for control, won't let a nameless nobody get a slice of the cake. But the dusty, poncho-clad newcomer has already set his sights on the grand prize--the only way to get it is to play the gangs off against each other in a deadly battle of wits. Of course, no one has pulled such a reckless stunt and lived to tell the tale. How far is a man willing to go for a fistful of dollars?
