The elder Defenders are lured to a mountain bunker in Colorado by Tycos and the Phantom is captured. Tycos then shuts down all computer circuitry in the Western Hemisphere, except for Tweak, who is impervious to Tycos' efforts because of his non-silicon makeup. The young Defenders' plea for Audie's assistance falls on deaf ears; however, the fact that they come to his rescue when he is captured by Ming persuades him to help our heroes. Arriving at the mountain bunker, the youngsters discover that Mandrake and Flash are also Tycos' captives. Tweak enters first, sacrificing himself to dismantle the nerve gas which frees the three heroes and clears the way for the others to join in the effort.
