Sketch Paree and The Mole are hypnotizing well-to-do customers at the amusement park, and then taking all their money. Dick Tracy sends Go Go Gomez to the park, disguised as a multimillionaire, to foil the two crooks. Sketch finally corners his prey and begins to put Gomez under his evil influence. Tracy comes on the scene and places a mirror in front of the villain's eyes. Soon, Sketch Paree is under his own trance, and is completely unconscious.
