 Spidey s old enemy from  Swing City  - the Radiation Specialist - is back! This time, he is much darker - even psychopathic. Following his release from jail, the specialist promptly revisits Manhattan s nuclear reactor, stuns the outdoor soldiers guarding it, and again commandeers the reactor. Realizing Spidey still poses a threat to him, the specialist contrives a scheme using a remote-controlled car to get Spidey off the island. Spidey soon finds out about the specialist s plans and gets back into Manhattan, even as the specialist lifts Manhattan into the sky once again. However, the specialist s radiation has corrupted even the police - usually Spidey s friends - except for Captain Stacey, whose strong mind has immunized him against the specialist s radiation. When Spidey is captured after falling into the streets from an earthquake, Stacey implements a plan to help Spidey escape. Spidey heads to the reactor for another confrontation with the radiation specialist, who tries this time to enslave Spidey himself. Spidey, however, resists the radiation and kicks the specialist in the head. The specialist fires his gun at Spidey, who ducks, and the ray from the gun hits the instruments sustaining the anti-gravity ray, sending the island plummeting back to earth. Spidey must neutralize the specialist & his radiation quickly before thousands of people are killed.
