Land of the Lost is the story of a forest ranger and his two teenage children who fall through a time vortex into another universe. They try to return to our universe, but their lives are constantly endangered by dinosaurs, the ‘Sleestaks', seven-foot tall hissing lizard people who live in an underground city and the Land of the Lost's peculiar laws of physics. They also befriend the ‘Pakuni', a small tribe of ape-like creatures.
