A "death contract" from fifty years ago drags urban youth who returned home for funerals into a supernatural injustice case in a northeastern mountain village that spans two generations.
Intention: A true "snow burial" is not to bury sins in the soil, but to let the whole village bury the innocent souls with fifty years of silence. What is engraved on that old wooden sign is not a name, but a "sealing contract" signed by a living person on behalf of a dead person; there are no minions who knock on the window at night, it is a period of history that has been collectively swallowed, knocking on the door of the present world. When the descendants dig out the white bones from the snow for their elders, what they are digging out is not the graves of their ancestors, but the conscience of an entire era that is ashamed to speak of it. So this is not a ghost story, it is the living "reviving" the dead, and the living owes the dead a fifty-year "reporting money". When the snow melts, the debt will not melt; when the person dies, the debt will not die.
