Anticipating a number of twentieth-century inventions, Jules Verne creates a science-fiction masterpiece in 20,000 Leagues Under the Sea. Professor Aronnax and his servant set out to eradicate a sea monster that has mysteriously destroyed hundreds of vessels. When the monster attacks their ship and knocks them overboard, Aronnax, his servant, and harpooner Ned Land discover that the "monster" is in fact a fantastic underwater ship Nautilus, manned by the crazed Captain Nemo.
