Forest ranger Rick Marshall and his two kids, Will and Holly, are on a routine expedition when they're swept into an alternate universe known as the Land of the Lost. There, they must learn to survive in a strange new world inhabited by strange monkey people, dangerous giant lizard-like creatures, and massive earthlike dinosaurs while learning to master mysterious Pylons, which may be the key to finding a way home.
Rick, Will, and Holly Marshall find themselves stranded in the Land of the Lost and become fast friends with a young Pakuni called Cha-Ka after rescuing him from a bully named Grumpy.
Will and Holly experiment with the colorful crystal matrix table inside the pylon, causing apocalyptic weather conditions. The Marshalls must quickly learn to turn the atmosphere back to normal before the extreme weather destroys the Land of the Lost.
