Synopsis
In the late 19th century, as humanity embraces technological advancement, a shadowy organization led by Gargoyle threatens world domination. Gargoyle seeks to revive the lost Atlantean empire.
Nadia, a mysterious girl, joins forces with Jean, a bright young inventor.
Together, aided by the enigmatic Captain Nemo and his advanced submarine, the Nautilus, they embark on a perilous journey to thwart Gargoyle's nefarious plans and protect the world from the resurgence of Neo-Atlantis.
Their adventure is inspired by Jules Verne's classic novel, 20,000 Leagues Under the Sea.
