Nadia: The Secret of Blue Water - Season 1 Episode 7 The Tower of Babel
7.50 25 minutes Imprisoned by the wicked Gargoyle, Nadia is forced to admit that she gave her Blue Water to Jean before turning herself in (to save Marie and King from a horrible fate). As the search for Jean is on, the boy desperately tries to find her. Simultaneously, Grandis, Sanson, and Hanson, who have also been imprisoned by the soldiers, break out of their prison cell and attempt to escape. While Gargoyle tours Nadia around his base, he showcases Neo-Atlantis's secret weapon, a tower known as Babel with the power to obliterate an entire island!
