Down in a village called Cavevill there were two cave children named Ook and Gluk. Their chief was was very mad all the time. It's because once he makes something better—like when their chief makes a tire—Ook and Gluk make motorcycles. Then the chief gets mad. So they make a time portal and go to the future and get a ton of ideas to show off, but then they get chased by the chief into the future. Then they find a Kung Fu place and stay there for the rest of their lives.
