Protected by a high-tech aerial umbrella, Jonny Quest accompanies his father, Benton, to Antarctica, where the elder Quest intends to look into another baffling mystery. This time, a missile has gone off course for no discernable rhyme or reason. Things get hot in the snowy wastes for Jonny, Benton, Race Bannon, and Hadji when a gang of enemy spies try to put the heroes "off course" as well -- permanently. "Antarctic Splashdown" was originally telecast on September 25, 1964. ~ Hal Erickson, Rovi
