While preparing a report for a redevelopment project, real estate planner Lin Wan entered an urban village slated for demolition to conduct a survey. There, she discovered strange scale-like patterns on the bodies of villagers who had died under mysterious circumstances.
Trapped in a condemned building on a stormy night, she witnessed half-human, half-snake creatures moving between the buildings. Her phone captured their inhuman pupils and flickering tongues, before all electronic devices suddenly stopped working.
After meeting Fang Qingye, a descendant of tomb guardians, she learned that the place was a thousand-year-old snake burial mound. The developers had blown up the stone that sealed the tomb, allowing demonic energy to escape. The living were undergoing a transformation like a snake shedding its skin.
Fang Qingye tried to seal the tomb with a family heirloom, but the developers stood in his way. At death's door, Lin Wan discovered a mysterious connection between her bloodline and the snake burial mound, forcing her to confront her most primal fear of survival.
