20,000 Leagues Under The Sea

Jules Verne's classic science fiction story Twenty Thousand Leagues Under the Sea tells the great tale of Captain Nemo and his submarine Nautilus. In 1866 a strange and unknown sea monster is sighted by ships and an ocean liner is attacked. An expedition prepares in New York, to find and destroy the menacing creature. The 20,000 of the title refers to an overall distance traveled under the sea, rather than an impossible measure of descent.
A deadly and huge sea monster is sinking ships. Three men--a French scientist, his trusty sidekick, and a Canadian harpoonist are thrown from the deck of their American warship. A door opens on the side of the monster, and they are taken inside the greatest submarine in the world, the top-secret Nautilus commanded by a madman who will take them 20,000 leagues into the depths.
