 At a banquet, a prominent scientist named Dr. Irivng Caldwell is to receive an award for his newest creation - the Astro-Helmet, which has the ability to levitate the user. But Caldwell vanishes, literally, in a bolt of lightning. A psychopath named Dr. Zap has kidnapped Caldwell to duplicate the Astro-Helmet for his own evil use. Caldwell s son, Jan, is drawn into a trap by Dr. Zap, who orders him to go to Lightning Mountain with the Astro-Helmet. When Peter spots Jan - dubbed  Skyboy  by the Daily Bugle - he confronts him, and the two of them decide to team up to confront Dr. Zap at Lightning Mountain. Dr. Zap, however,  zaps  Jan with electricity, and brings him & Spidey into his lair when Spidey goes to help Jan. Jan is reunited with his father, but Spidey is caged inside a plastic bubble. Enraged, Spidey hammers on the glass, which gets Zap s attention. Realizing he still has his camera, Spidey fires the flash at Zap several times, driving him back. The oriental villain backs into his own electrical transformers & short-circuits them. Jan, Dr. Caldwell, and Spidey narrowly escape before a final, huge explosion destroys Dr. Zap and his lair.
