A strange man, Captain Nemo, disillusioned by social injustice, decides to live in his own world.

He builds a bizarre ship, the legendary "Nautilus," that could sail beneath the surface of the sea, from one corner of the Earth to another, and sink ships sailing in the oceans with its ram. Sailors and citizens around the world are terrorized by what they all thought was a huge, wild whale.

Eventually, they decide to organize a special mission to hunt the monster. Famous personalities join the mission. A special advisor to the Navy, Professor Aronnax, and the renowned whaler, Ned Land.

They scour the seas but do not catch a glimpse of the sea monster anywhere. As the months pass, the sailors begin to show signs of unease. They want to return to their homeland.

But just as they are ready to head back, Ned suddenly shouts that the monster is coming toward them. And from that moment on, the great adventure begins.
