"Land of the Lost" details the adventures of the Marshall family (father Rick and his children Will and Holly), who are trapped in an alternate universe or time warp inhabited by dinosaurs, a primate-type people called Pakuni, and aggressive humanoid/lizard creatures called Sleestak. The series opens with a theme song accompanied by a banjo like instrument and a synthesizer. The episode storylines focus on the family's efforts to survive and find a way back to their own world, but the exploration of the exotic inhabitants of the Land of the Lost is also an ongoing part of the story.
