In this western, two disparate twins ride the range. One is a real troublemaker while the other is a government agent. When the bad brother is sent to prison, the good one begins posing as him so he can capture two outlaws. He does so, but then finds himself accosted by an angry dance-hall girl who says that he (the bad brother) had promised to marry her. The good brother's girl friend has a thing or two to say about that and romantic mayhem ensues.
