Through recurring dreams guided by a magical pool, Belle discovers that the Beast was once a human prince married to a gorgeous princess who was actually a forest nymph and daughter of the Forest God. The nymph could turn into a Golden Doe and made him promise never to hunt her. Breaking his vow to satisfy his hunting obsession, the Prince shot the Golden Doe with a golden arrow, only to watch her transform back into his dying wife. The colossal Forest God subsequently cursed the Prince into a beast, turned his hounds into sprites (Tadés), transformed his companions into stone giants, and placed the domain into an eternal magical winter.
When Belle returns home to visit her ailing father, Perducas and Belle's debt-ridden brothers learn of the castle's immense wealth and invade it. The Beast awakens the colossal stone Titans to crush the invaders. Perducas mortally wounds the Beast with the original golden arrow before being consumed by magical briars. Belle and her brothers carry the dying Beast to the glowing spring of life inside the castle, where Belle declares her love, breaking the curse. The Beast turns back into a human, the estate blossoms, and the ending reveals Belle as the storybook narrator living happily on a humble flower farm with the Prince and their children.
