Passing Through (1921)

Billy Barton a bank teller, shoulders the blame for a cash shortage for which Fred Kingston, a fellow employee, is responsible and is sentenced to prison. On his way there, the train is wrecked and he escapes. In the town of Culterton, he meets and falls in love with Mary Spivins, the bank president's daughter, and charms the populace by playing the mouth organ. He obtains work as a farmhand with Silas Harkins, taking the farm mule as wages. When Spivins orders Harkins arrested for assault, Billy learns it was a kick from the mule that laid out Spivins. At the bank he finds Spivins bound while Fred and the clerk are robbing the safe; Billy is locked in the safe, and all efforts to save him prove futile until the wall is kicked out by the mule. Through the efforts of Willie Spivins, the bank is dynamited, but all ends happily.
