El Rostro Impenetrable

After successfully robbing a bank in Sonora, Mexico, Dad Longworth abandons his surviving partner, Rio, who is caught and imprisoned by the Mexican Federales. Five years later, Rio manages to escape and wants his revenge. He soon learns that Dad Longworth is now the Sheriff of Monterey, California, where there also happens to be a bank just waiting to be robbed. Longworth has done well for himself: He's just been re-elected Sheriff, and is now married and has a lovely stepdaughter, Louisa. As Louisa and Rio fall in love, killing Longworth becomes more of a problem, but the Sheriff makes it easier by arresting Rio for robbing the bank--which he didn't.
