Synopsis:
Jimmy Olsen learns that Professor Worthington has discovered a new asteroid near Earth. Before Worthington can explain why he has named it the Olsen asteroid, the professor is killed by a disintegration ray. Jimmy checks the professor's research and finds evidence that the asteroid is inhabited by duplicates of him. Then a spacecraft lands which offers him a ride to the asteroid.

Jimmy takes the ship to the asteroid and finds many varieties of Olsens. Some are normal in appearance while other mimic some of his freakish transformations. Some of the Olsens are good while others are evil. When Jimmy claims to be the real Olsen he is arrested.

Jimmy escapes from jail by disguising himself. He is then aided by one of the good Olsens. He discovers that Tempus the clock maker is responsible for the asteroid and the Olsen doubles. Tempus blames to destroy Earth by crashing into it with the asteroid. Jimmy is able to destroy the mechanism which powers the robot doubles and the asteroid. After Tempus is defeated, Superman arrives to take Jimmy back to Earth.
