Rick Marshall and his children Will and Holly are on a weekend expedition rafting down a river when an enormous earthquake diverts them to an eclectic alien world inhabited by dinosaurs, chimpanzee-like cavemen called Pakuni, and aggressive, humanoid lizard creatures called Sleestak.
Will and Holly save a Pakuni ape-boy named Cha-Ka from Grumpy the Tyrannosaurus Rex.
While searching the Lost City, Will and Holly are captured by lizard-men which are known as Sleestak.
A troublesome baby brontosaurus follows Will and Holly home.
The Marshalls attempt to escape the Land of the Lost by river and wind up trapped in a cave with a daffy Confederate miner.
While fleeing from the jaws of dinosaurs, the Marshalls and the Pakuni are forced to work together.
The Marshalls meet Enik, an intelligent, time-traveling relative of the Sleestak.
Will and Holly are lured to the Lost City by a hypnotic stone which shows them a vision of their dead mother.
When Will and Holly find a way into a pylon, they discover a device which summons a terrible storm.
Rick joins forces with an intelligent Sleestak when they end up rooming together with the hungry Sleestak God in the Hole of No Return.
Cha-Ka is invited to dine with the Marshalls. Meanwhile, Holly's perfume drives the locals wild!
