Synopsis:
Jasonar, a scientist from the extradimensional world of Kalanor, flees to Earth to escape the tyrant Despero, and the perfect a secret weapon to defeat the mutant villain. Here he encounters the Flash, who summons the Justice League to his aid.

Despero, however, learns of this, and places the League members, except the Flash, in a hypnotic trance. Then he challenges the speedster to a chess-like game, rigged in his favor. Flash loses, and therby condemns himself and his fellow members to be teleported to another dimension. Wonder Woman and Superman find themselves on a prehistoric planet, Aquaman and Green Lantern on a water-world whose seas are drying up, and Batman, J’onn J’onzz, and Flash on a world whose sun is about to go nova due to Despero’s machinations.

Overcoming these various perils, the super-heroes return to Earth, to find that Despero had been defeated by Snapper Carr, using Jasonar’s secret weapon.
