At the famous Rockefeller Center skating rink; the web-slinger, Will-O'-the-Wisp, and spider-slayer assemble for a tripartite throw down! Once the Wisp flees the scene, Spidey puts Jonah's spider-slayer on ice! Later that evening in Times Square under coercion from Dr. Jonah Harrow, Will-O'-the-Wisp attacks Spider-Man! If the Wisp doesn't kill the web-slinger, he will lose his life! If he does kill him, the Wisp will lose his humanity! Caught in a diabolical dilemma, what will the Wisp do with the wall-crawler's life hanging in the balance? A gut-wrenching conclusion! Cameo appearances by Dr. Marla Madison and Mary Jane Watson.
