Synopsis:
While Hal Jordan is visiting his brothers in preparation for Jim's wedding to Sue Williams, J. Charles Gantner threatens the city with electrical energy. The district attorney Jack Jordan and the police plan a trap for Gantner, and Hal follows as Green Lantern. Gantner evades the trap, and GL is surprised from behind and knocked unconscious.

Believing Jim Jordan is really Green Lantern, Sue Williams orders him to go into action against Gantner. Jim tries to reason with Sue, but eventually decides to humor her. However, Jim stumbles upon Gantner's hide-out accidentally. When Gantner tries to use a weapon on Jim, the Jordan brother tries using will power to overcome the villain. Green Lantern regains consciousness at that moment and knocks out Gantner. Since Jim never saw GL, he takes credit for the capture.

Jim and Sue then get married with Sue still convinced that her new husband is really Green Lantern.
