Based partially on Jules Verne's 20,000 Leagues Under the Sea, Nadia: The Secret of Blue Water begins as Jean, a young French boy who builds airplanes, teams with his uncle to enter a flying competition at the 1899 World's Fair in Paris. It's there that the preteen Jean meets and immediately falls for the exotic Nadia, who leads an unhappy life as a circus performer.
Jean turns protector when Nadia is chased by a trio of bumbling villains who are after the mysterious "blue water" in Nadia's necklace. Their pursuit leads to the open sea, where Jean and Nadia board an American battleship searching for a vengeful sea monster, ultimately revealed as Captain Nemo's submarine, Nautilus.
