Dr. Marsh Tracy (Marshall Thompson) is an animal behavioral research director who travels to East Africa with his daughter Paula (Cheryl Miller) in this engaging wildlife saga. While Tracy develops a relationship with anthropologist Julie Harper (Betsy Drake), Paula befriends the visually challenged lion named Clarence. Because his eyes are crossed, Clarence has never been able to rely on hunting for survival, so the family adopts the lovable lion. Richard Haydn plays the schoolmaster with comic flair as he runs scared from the harmless king of the jungle. The evil Gregory (Maurice Marsac) is the leader of a group of mercenaries who plan to capture Julie's beloved gorillas and sell them for profit. Clarence later traps Gregory in a slapstick scene to save the animals from danger. The film served as a pilot for the television series Daktari.
