The film tells the tale of the adolescent son of two wealthy socialites who have left him home alone while they go out on the town. At home, the boy begins a series of wild daydreams. He finds himself aboard an elevator that takes him through the Earth and onto another planet. There he finds the "Nautilus," Captain Nemo's submarine. He also finds Nemo's ape/man assistant. Together they begin a series of spectacular adventures. They encounter many storybook characters along the way. ~ Sandra Brennan, Rovi
