The French naturalist Professor Aronnax, along with his faithful servant Conseil, and the tough whaler Ned Land, join an expedition to discover a sea monster that is spreading terror across the world's oceans. However, the only thing they will discover is the Nautilus, the submarine of the enigmatic Captain Nemo, who, in order to keep his existence a secret, captures the three men. In the following months, the professor and his companions will visit the lost Atlantis, fish for pearls, face a giant squid, be attacked by a tribe of cannibals, and experience incredible adventures in the depths of the oceans.
