Betty and Fitzhugh are caught in a paralyzing trap and taken away by a SID officer to an interrogator named Marad. Suddenly, they are teleported away to the home of Professor Kirmus who has developed a matter transport device capable of sending anything anywhere—including the little people back to Earth. Unfortunately Kirmus's housekeeper is really a SID operative and she turns Kirmus in to the authorities, but Marad is really after the secrets of the teleport machine. Meanwhile, Steve and the other Earthlings search for a missing component of the device hidden by Kirmus, who promises them a trip back home.
