The Gnome-Mobile synopsis
While driving through the forest with his grandchildren, Elizabeth (Karen Dotrice) and Rodney (Matthew Garber), lumber tycoon D.J. Mulrooney (Walter Brennan) stumbles across a duo of tiny gnomes. When the lumber company's head of security (Richard Deacon) hears the story, he thinks that Mulrooney has lost his mind, and he has him committed. Now the grandchildren need to free the old man and also rescue the little gnomes, who were kidnapped by a freak-show promoter.
