Tim and Tam are kidnapped right off of the space station by ice glob soldiers of Dr. Krangak from the planet Zero. Craig pursues them in a spacemobile, but he too is captured. Krangak subjects the teens to a mind control ray and sends them to the planet Raynoid to penetrate a defense ray and capture the designer. Tim and Tam succeed. But Craig has escaped his cell and renders Krangak unconscious. He radios to his mind-controlled children to release the Raynoid scientist. They return to planet Zero, rescue their father, and return to their space station.
