Stanley goes with his family and friend's to his great uncle's dude ranch. The local land baron is trying to buy the ranch and make it a parking lot for his nearby amusement park. The only way Uncle Stew thinks he can get any money to save his ranch is to find other dinosaur bones to attract customers. Stanley and his friends help in the search.
