In this enchanted swashbuckling tale of two lovers cursed to live together yet apart. With the help of the wily Phillipe Gaston, known as the Mouse, the lovers battle the evil bishop.

Upon breaking out of a dungeon, youthful thief Phillipe Gaston (Matthew Broderick) befriends Capt. Navarre (Rutger Hauer), a man with a strange secret. Navarre and his lover Lady Isabeau d'Anjou (Michelle Pfeiffer) were cursed by the wicked Bishop of Aquila (John Wood), who desires Lady Isabeau for himself. His dark magic prevents the pair from ever being in each other's presence except at twilight, so they enlist Gaston in a dangerous plot to overthrow the Bishop and break his evil enchantment.
