 Agents West and Gordon are engaged to rescue an Indian Chief s abducted daughter before the Indians retaliate. The agents learn that the miniature Dr. Miguelito Loveless, responsible for the kidnapping, has a plan to rule a land of little people, with the help of a powder he invented to reduce the size of people. During the rescue mission, Loveless shrinks Jim and the Indian Princess to a height of six inches, leaving them to defend themselves from the mad doctor s now gigantic cat and raven.
