Big Jim Kennally ran an organization that made counterfeit money in the 1870s. He had a big problem: His best counterfeiter, Ben Boyd, was in prison. Boyd made metal plates that would stamp the image of money on paper. And it was almost impossible to tell Boyd's fake money from the real stuff.The Secret Service, which now protects the president but got its start investigating counterfeiting, eventually caught Boyd and sent him to prison. As a result, Big Jim couldn't make fake money. He had to come up with a plan to set his guy free.
