Originally telecast September 18, 1964, "The Mystery of the Lizard Men" was the third episode of Jonny Quest to be filmed, but the first one to be shown. Dr. Benton Quest is called in to investigate when five fishing boats are blown out of the Sargasso Sea. According to survivors, the ships have been destroyed by a mysterious light beam. Naturally, Quest's son, Jonny, finds himself in the thick of things when the laser-wielding villains -- frogmen dressed in lizard suits -- rear their ugly heads. ~ Hal Erickson, Rovi
