Five miles of drilling later, the Krank Tank bursts from the ground in the middle of Manhattan. The three Krank brothers, rulers of a civilization in the Earth's core, have arrived on the surface with every intention of taking the whole thing. Earth's last defense is the Kore Suit, invented by Dr. Samuelsen before he was captured and dragged into the tank. Three unlikely heroes — Pixie, Madboy, and Rex — must infiltrate the vehicle, find the suit, and stop the Kranks before they locate the doomsday device they forgot to bring along and install it.
