Lin Shen, a geology student, returns to his hometown with his girlfriend Su Tang, only to discover that GPS shows the village lying beneath a reservoir a hundred meters deep. A blood-red stone stele is covered in names on a sacrificial list. At night, a Republican-era bridal gown crawls into their suitcase by itself, while the villagers’ pupils reflect the red wedding candles of a ghost marriage from a century ago. Only when Su Tang sees seven rotting brides who look exactly like her in a phone photo does she realize the entire village is alive. A Nine Yin feng shui formation devours outsiders to prolong its own life, and she is the final blood-red sacrifice in a century-spanning conspiracy to steal her fortune.
