Before her death, grandma held Lin Jian's hand tightly: "The red light at the entrance of the village... Must, must watch it!"
As a student in the Department of Archeology, Lin Jian only thought that this was the old man's obsession. It wasn't until he took over the mottled paper lamp that he realized that what grandma was guarding was not a lamp, but a lock.
The red light goes out and the contract is terminated. So——
Under the frozen river surface, a line of "pale water ghosts" emerged; in the abandoned mines, neat "collective footsteps" came; on the felled old mountain spirit trees, warm blood dripped...
Every page of the notes left by grandma is a survival rule crossed out in blood:
"When you hear the night wedding suona, don't peep, you must recite the factory song behind closed doors."
"If you see a person without footprints in the snow, don't answer him and walk three steps against him."
"When the red light ignites spontaneously, the evil is behind you..."
In order to survive, Lin Jian must form an alliance with the shaman girl who has lost her supernatural power and the old hunter who is full of lies. In the desperate situation where the mountains are blocked by snowstorms and communications are cut off, Lin Jian must uncover a blood debt that has been frozen for sixty years. What they face is not only the vengeful dead souls, but also their "hometown" that has long been changed beyond recognition, nourished by the greed of the human heart.
