In 15th century Paris, Clopin the puppeteer tells the story of Quasimodo, the misshapen gentle-souled bell ringer of Notre Dame, who was nearly killed as a baby by Claude Frollo, the Minister of Justice. But Frollo was forced by the Archdeacon of Notre Dame to raise Quasimodo as his own. Now a young man, Quasimodo is hidden from the world by Frollo in the belltower of the cathedral. But during the Festival of Fools, Quasimodo, cheered on by his gargoyle friends Victor, Hugo, and Laverne, decides...

Now that Frollo is gone, Quasimodo rings the bell with the help of his new friend and Esmeralda's and Phoebus' little son, Zephyr. But when Quasi stops by a traveling circus owned by evil magician Sarousch, he falls for Madellaine, Sarouch's assistant. But greedy Sarousch forces Madellaine to help him steal the Cathedral's most famous bell.
