Synopsis by Janiss Garza
In the more naive times of the 1920s (at least when it came to narcotics), drug store cowboys had nothing to do with drugs. Instead, this comedy-melodrama focuses on Marmaduke Grandon (Franklin Farnum), who's a drug store clerk with aspirations to be a movie star. He gets his chance when an actor suddenly dies and he is asked to take the man's place. Grandon's role is the villain in a Western, but on his way to the set he runs afoul of a real bad guy, Gentleman Jack (Robert Walker), who insists on changing clothes with him. So Grandon finds himself on the run from the law, while Jack takes his place in the film. Grandon keeps showing up on the set, attempting to save the leading lady (a very young Jean Arthur) from Jack, and ruining the takes. He turns out to be a hero when Jack uses one of the film's scenes to rob a bank for real. Grandon captures him, and their identities are finally revealed. He finally gets his acting role, and wins the leading lady as well.
