When a space station orbiting Earth goes silent, Gadget must investigate. Penny and Brain tag along aboard the space shuttle that takes Gadget to his destination, where Penny discovers that the station's soft-spoken HAL-like supercomputer is under the control of two M.A.D. agents, Dr. Null and Dr. Void. Their evil plot involves a giant magnifying glass that can aim and intensify the sun's rays towards Earth.

M.A.D. gains control of Metro City's banks, by tapping into an orbiting satellite. With the added distraction of "Crazy Gas", a substance that induces hallucinations in their victims, can even Inspector Gadget ever hope to regain control of the city's bank accounts?
