Dr. Zin, the Quest team's perennial nemesis from the 1964-1965 run of Jonny Quest, returns in the October 5, 1986, episode "Deadly Junket." Kidnapping Jessie Bradshaw, the daughter of a prominent rocket scientist, Zin hopes to use the girl as a bargaining chip in his efforts to seize control of her father's rocket-brain technology. The plucky Jessie manages to escape, ending up in the protection of Dr. Quest and his son Jonny -- who soon begins to wonder why the resourceful girl would ever need anyone's protection. This "new" episode of Jonny Quest (1986 series) originally aired as a component of the weekend "Funtastic World of Hanna Barbera" package. ~ Hal Erickson, All Movie Guide
