On a rainy night, Lin Xia, a nurse in the emergency department of Xin'an Hospital, suffered a strange power outage. The refrigerator in the morgue burst, and Zhang Mingyu, a young man who was supposed to have died three days ago, woke up in the frost, with glowing snake-shaped symbols walking under his skin. The corpse left behind a bloody mystery and then mysteriously evaporated. The inhuman tooth marks under the cuffs of the security captain Zhou and the tampered surveillance system hinted at the dirty transactions deep in the morgue. When Lin Xia discovered that the same symbol appeared on her wrist, and even saw the smiling reflection of the "dead man" in the mirror, she was shocked to realize that the morgue that night was no longer a place on earth - the buzzing of the refrigerator turned into the frequency of hell, and the bloody symbol was dragging her into a century-long mystery of life and death. When the resurrected Zhang Mingyu stood alive in the morning light, Lin Xia finally saw clearly: what she caught was not the secret of the corpse, but the curse beacon handed over by the deceased across time and space.
