Paying a visit to his grandfather's ranch, Jonny becomes curious about a nearby biodome. Investigating, Jonny and his friend Hadji uncover a scheme hatched by a crooked businessman to build weapons out of uranium. Inside joke: Jonny's granddad is named Doug Wildey -- the same name as the celebrated comic-book artist who developed and nurtured the "classic" Jonny Quest series of the 1960s (the episode was in fact dedicated to the "real" Doug Wildey). "Nuclear Netherworld" originally aired on December 26, 1996.
