At the urging of his gargoyle pals, Quasimodo leaves the solitary safety of his Notre Dame tower against the wishes of his guardian, the evil Judge Claude Frollo. He ventures out to the Festival of Fools and finds his first true friend, a Romani woman named Esmeralda, who entrusts him with a secret. When the secret is revealed, Quasi soon finds himself fighting to save the people and city he loves.
The film is set six years after the events of the original film and the death of Claude Frollo. Captain Phoebus serves as Paris, France' Captain of the Guard under the new Minister of Justice. Phoebus and Esméralda (The Hunchback of Notre-Dame) have married and become the parents of a six-year-old son named Zephyr. Quasimodo is now an accepted part of Parisian society; though he still lives in Notre Dame de Paris with his gargoyle friends Victor, Hugo, and Laverne as the cathedral's bell-ringer.
