Scientist Bruce Kaine and his assistant Vina Talbot go to meet the President of the World, Roger Stanton. Roger was Bruce and Vina's teacher before ascending to the position of high power. Arriving at the office, Bruce thinks Roger is a bit distant. Bruce shows Roger the new magnet he's developed, but the magnet is instantly attracted to Roger. The jig being up, Roger reveals he is actually a robot named Z-13 who has taken the real President Stanton captive. Z-13 sends another robot, X-40, to capture the pair. Bruce and Vina escape the robot's clutches.
