A group of giant ice creatures situate in New York Harbor in their damaged, diamond-like spaceship and abduct Dr. Smartyr, a noted scientist. Spidey boards the alien space vessel, passes through a maze of perilous, icy tunnels, and finds the aliens' control room, where Smartyr, an expert in propulsion, is helping the creatures, friendly Plutonians who were forced to land on Earth for repairs to their spaceship. With his new invention, a space warp control device, Smartyr assists the Plutonians to launch their spacecraft out of New York Harbor, leave Earth, and return to Pluto. But neither Smartyr nor Spidey will tell anyone about their encounter with aliens.
