At 20,00 Leagues, the monsters are all around you. There is a sea monster on the loose and when Professor Arronax is sent to investigate, the beast damages his ship, leaving him adrift. To his surprise, the monster is actually a highly advanced submarine. He now finds himself the guest of the brilliant and charming Captain Nemo. However, as the charm fades and Nemo’s violent tendencies manifest, Arronax and his cohorts realize they are not guests, but prisoners beneath miles of ocean.
