Synopsis:
Superman battles an alien who uses super weapons against the Man of Steel. Jimmy Olsen helps Superman stop the alien who is caught in the blast of one of his own weapons. Superman tries to help the dying alien, who gratefully offers Superman a secret warning.

Later Horsehoe Harrigan visits the Daily Planet offices and offers money to charity if Superman will defy some popular superstitions on Friday the 13th. Superman appears hesistant and afraid of each task, leaving them to Jimmy. During the third task Superman warns everyone out of the area as a weapon materializes.

After the bomb fails to materialize and detonate, Superman explains that the alien warned him about a planned attack. Superman feigned cowardice so the aliens would go through with the attack, and he could stop it.
