The story is set in the early Qing dynasty. Zhuo Yihang of the Wudang Sect is in love with Lian Nichang, but Zhuo's fellows strongly oppose their relationship and cause them to break up. Lian is heartbroken and her hair turns white overnight. She becomes known as the "White Haired Demoness". Zhuo is unwilling to give up his love for Lian and seeks a rare flower that can turn white hair black again. However, the flower only blooms once every six decades. After a long search, Zhuo finally finds the flower on Mount Heaven, but it is accidentally destroyed by his apprentice, Xin Longzi.
