Bring Me the Head of Alfredo Garcia (1974) on Netflix

A family scandal causes a wealthy and powerful Mexican rancher to make the pronouncement--'Bring me the head of Alfredo Garcia!' Two of the bounty-hunters thus dispatched encounter a local piano-player in their hunt for information. The piano-player does a little investigating on his own and finds out that his girlfriend knows of Garcia's death and last resting place. Thinking that he can make some easy money and gain financial security for he and his (now) fiancée, they set off on this goal. Of course, this quest only brings him untold misery, in the form of trademark Peckinpah violence.
