The troupe of opera actress Su Qing unexpectedly received an invitation to perform in an ancient village in the mountains and designated to perform "Farewell My Concubine" in the village ancestral hall. Stepping into the mountain village, a strange atmosphere follows you: the villagers with pale faces and dull eyes, the lingering burnt smell in the ancestral hall, and the unknown sounds of drama echoing late at night. On the night of the performance, there was a sudden power outage in the ancestral hall, and the same aria as Su Qing sounded in the darkness. When the lights came back on, another "Su Qing" appeared on the stage, and all the villagers in the audience turned into faceless souls. It turns out that decades ago, a fire in the ancestral hall swallowed up the entire troupe of actors, and the dead souls were trapped and wanted to find living substitutes. As for the fire, the villagers decided that the theater troupe was "ominous" and deliberately set it on fire. Su Qing must uncover the truth and resolve her obsessions before the ghost play cycle ends, otherwise the entire team will become eternal sacrifices.
