The Justice League of America celebrates its 100th meeting with a gala party, and among the guests are Elongated Man, Metamorpho, Zatanna, and Diana Prince. No sooner does the affair begin than the heroes and their guests are summoned to Earth-Two to aid the Justice Society of America in overcoming a giant nebulous hand that is about to crush their planet to bits. Combining his magic with that of Zatanna and Johnny Thunder's Thunderbolt, Dr. Fate contacts Oracle, a cosmic entity who informs the heroes that only the Seven Soldiers of Victory can overcome the menace that threatens them. He also reveals that the once-famous crimefighting team had been scattered to various eras of Earth's past as a result of their battle with an energy-creature called the Nebula Man. Oracle then transports the heroes in search of the Seven Soldiers in three-man teams. Dr. Fate, the Atom, and Elongated Man find the Crimson Avenger possessed of strange powers in his new role as king of an Aztec tribe. Escaping the natives who battle to defend the former crusader, they restore his memory and return him to the present. Meanwhile, the Iron Hand, a villain once defeated by the Seven Soldiers, proves to be the mastermind behind both the Nebula-Man and the giant hand menace.
