In his efforts to save the life of King Louis, Quasimodo must hurry to reveal the identity of an assassin hidden amongst the costumed guests at the Palace Masquerade Ball.
After finding an ominous note tied to the leg of a wounded carrier pigeon depicting a war machine with the caption "...complete world domination," Quasimodo and friends head off in search of the mystery sender.
From his secret cave hide-out at a place called Dragon Rock, Frollo positions his "mountain-smasher" to destroy a town in order to build himself a fortress.
When King Louis suddenly raises taxes, throws innocent citizens in prison and plans to surrender Paris to the Duke of Burgundy, Quasimodo suspects this "King" may actually be an impostor.
At first Quasimodo is denied entry in the army because of his physical handicap, but he not only proves to be a good soldier, he saves France from a horde of vicious barbarians.
Quasimodo, Esmeralda and Francois discover an old hermit with an enchanted carillon, living in the woods. Each time he plays its beautiful music, an apparition appears.
Legend holds that when the last piece of glass is installed in the new hospital, sunlight will shine through and reveal the coded location of the Philosopher's Stone.
Francois is suddenly abducted by the ancient order of the Knights Templar. Quasimodo and Esmeralda are unable to save him, but a clue left behind leads them to a long-abandoned chateau, where they are stunned to find Francois a most willing captive.
