Hans and Heinie are broke. Hans concludes that, having once been a horse doctor, he can cure human beings. He brews bacterium of a disease called the jumps. They inoculate the folk of a village with the jumps, and hang out a sign specializing in a cure for jumps. Their office is besieged. They make instant cures and incidentally a barrel of money but their trick is finally exposed. They are arrested, and jailed much to their discomfiture, but to the amusement of those who witness this wonderful get-rich scheme of Hans and Heinie.
