The Small Town Guy (1917)

Coaxed by sharpers, who seek to profit by his rustic innocence, the boy from the small town goes to the city with them and become, innocently enough, a successful swindler, but he learns of the deception and returns home, too ashamed to seek his old sweetheart. The crooks return to try a blackmail game, but Ernie's eyes are opened now. He cleans up in whirlwind fashion.
