A strange triangle shape in the sky has appeared over various cities of the world, and people are suddenly snapping into violent and antisocial behavior before vanishing without a trace.

"Superman created by Jerry Siegel and Joe Shuster, by special arrangement with the Jerry Siegel family."

Jody Cahill and some friends sneak into his father’s amusement park after hours. They find one of the workers dead on the ground, and the Phantom Stranger appears and warns them about stumbling around through the park.

Three young girls are gathered in a nightclub, and one of them is invited to dance with a man called Tannarak. Shortly after, the girl drops dead, and her death brings both Dr. Thirteen and the Phantom Stranger to investigate the situation.

When three friends die in a plane crash, their spirits seem to be haunting those they left behind, but the Phantom Stranger reveals that the ghostly appearances are really the work of an embezzler attempting to cover his tracks.
