The household helper robot, designed by Ming the Merciless in another of his evil schemes, is the hottest selling item on the market, deployed in over one million homes worldwide - including Monitor. Ming plans to use the robots to hypnotize their owners and make them his slaves. At the behest of Jedda, Rick examines his robot and discovers the plot, alerting the Defenders. When Flash flies out to space to destroy the satellite, a tractor beam renders his ship powerless and drags him towards Ice Station Earth! Splitting up, Lothar, Mandrake and the Phantom penetrate Ming's fortress to save Flash. While Ming captures the Jamaican and the Magician, the Phantom wreaks havoc on the robot production lab. Rick mobilizes his frequency inhibitor, overloading the household helper robots and rendering them useless. Back at Ming's fortress, Mandrake uses telekinesis to overload the main generator, enabling the Defenders to escape.
