"Things begin to happen when Johnny Wiggins breaks loose!"

Johnny Get Your Gun

While Bill Burnham is jailed for drunkenly shooting up the town, he receives a letter saying that his father has died, his sister Janet is about to marry a worthless count, and the family fortune is in danger. Unable to leave, he convinces his friend, Johnny Wiggins, a motion picture cowboy, to go to his home in Palm Beach, which Bill left as a boy, and impersonate him.
