This story is continued from Justice League of America #29.

Synopsis:
Taking care not to come into prolonged contact with their foes, les they be vibrated into Earth-3, the Justice Society members grapple with the Crime Syndicate. Hawkman defeats Johnny Quick, Dr. Fate overcomes Power Ring, Dr. Mid-Nite gets the best of Owlman, Black Canary beats Superwoman, and Starman outwits Ultraman. However, this time the villains have switched their strategy, and the mere act of claiming victory over their foes shifts the heroes into Earth-3, and they are imprisoned while the Syndicate stages a rematch with the Justice League.

This time each hero faces his counterpart, and defeats him by increasing the villain's powers beyond the point of control. The Crime Syndicate is incarcerated in the transition zone between Earths, and the JSA is freed.
