Synopsis:
The gang of Doc Morhar raids a chemical plant to steal rare chemicals. Robby Reed follows the crooks as King Viking. Robby smashes into their hide-out while Morhar is performing a chemical experiment. An accidental chemical spill causes Robby and the crooks to shrink into a microverse.

Robby encounters a race of sentient microbes bent on dominating the Earth. He tries to enlist Morhar's help in stopping the microbes, but the crook turns on him. Robby, in the super-hero form Go-Go is captured.

Doc Morhar leads the microbes to Earth and explains how to take over the planet. Robby becomes another hero, Whirl-I-Gig to escape his prison. Then he returns to normal size and defeats Morhar and the microbes.
