General Galt, anxious to know the source of Tekno-power, sends Balzac to infiltrate the Space knights in the guise of a war correspondent. Meanwhile, the aliens are attacking Earth with the computer controlled Space-Ring laser cannon. Commander Jamison tells the Space Knights that they must alter the computer's laser-control program without attempting to destroy the computer. If the computer is damaged or destroyed, its back-up system will switch on all the lasers and the Earth will be destroyed. Balzac accompanies the Space Knights on their mission. After boarding the Space-Ring, a fight between the aliens and Teknoman sets off the back-up system, and Balzac is the only one who can figure out how to disable the system.
