There is a village by the Yellow River, where ancestors have relied on the river for food for generations.
But there is a rule in the village: after the cold flood every year, no one can look into the "eye of the river".
Zhou Du does not believe in evil.
Until the first day when he returned to his hometown, on the way to send his grandmother for burial, he saw a corpse that looked exactly like himself floating up in the river.
Since then, the old folk customs along the Yellow River have come alive.
He Bo gets married, night lights lead the way, rules for fishing out corpses, the Dragon King suppresses evil spirits, and the resurgence of the old village...
Behind every legend, there is a secret buried by floods and people's hearts.
What Zhou Du didn't know was that his father who disappeared twenty years ago did not die in the river.
He was left in the river.
