Synopsis:
Jimmy Olsen volunteers for an experiment which allows him to go back in time and assume the bodies of men for which he is genetically similar. In one of his past lives, Jimmy was Janus, a friend of Julius Caesar. Jimmy learns that he betrayed Caesar and allowed the ruler to be assassinated.

In another of Jimmy's lives, he was Sir Oliver, a knight who served Richard the Lion-Hearted. During a battle, Jimmy was ordered to protect Richard, but he fled. Richard's attack succeeded, but the king was fatally wounded as a result of Jimmy's desertion.

Jimmy then takes the place of a Civil War soldier. After the war, the soldier is posted as a guard outside Ford Theatre while President Lincoln is watching a play. Jimmy falls asleep on guard duty and allows John Wilkes Booth to enter and kill Lincoln.

When Jimmy returns to the present he is disturbed that he brought about the downfall of great men. He worries that the same will happen to Superman, so he goes into exile. However, the Man of Steel tracks Jimmy down and explains the truth to his friend. Jimmy was really acting as Caesar's spy by infiltrating the senators, but despite Jimmy's warning to the guards Caesar was killed anyway. Jimmy's apparent desertion of Richard the Lion-Hearted was also heroic as Jimmy sacrificed himself to stop an enemy catapult. Finally Jimmy falling asleep at Ford Theatre was intentional in order to get Booth to show himself, but the other guards inside the theatre failed to stop the killer. Jimmy feels exonerated of wrongdoing in his past lives and returns to civilization.
