The Quests are in Africa, where Dr. Benton Quest intends to use a state-of-the-art weather balloon for an experimental flight deep into jungle territory. The balloon lands atop an otherwise inaccessible mountain peak, currently the domain of a snarling Nazi war criminal named Von Dueffel. The heroes find their lives in dire jeopardy when they discover that the villain is forcing the local natives to work his diamond mine. "The Devil's Tower" made its ABC network bow on February 4, 1965. ~ Hal Erickson, Rovi
