Her grandmother's last words before her death, "Don't touch the willow leaves, stay away from Gaohu", accidentally caused A Lan, who returned home to attend the funeral, to be accidentally involved in the family's three-hundred-year fateful curse. The willow pattern on the wrist, the strange sixteen bowls of blood sacrifice in the wooden house, the indifferent warning from the cousin Erzai, and the mystery of the seclusion of the sister-in-law Lin Xiu all point to the water evil spirit sealed at the bottom of the high lake - and she is the successor of the willow leaf bloodline that must be sacrificed in this generation.
