Plot
J.J. Manx is an unsuccessful businessman who robs banks in order to pay his employees. Oom Willie Swanepoel is a train driver who is skilled at playing the stockmarket. Neither of them know that they are in fact identical twin brothers.

When Swanepoel's activities cause the value of Manx's shares to drop, Manx locates Swanepoel and has him kidnapped. He then assumes Swanepoel's identity to steal the Bottomley Diamonds. Swanepoel's friends locate the diamonds and claim the reward money, using it to ruin Manx. Manx confesses his crime to the police but it turns out the diamonds were fakes, part of an insurance fraud.
