A bride vanishes from her bridal sedan, leaving only a wooden statue. Carpenter Li Mudun is framed for the crime. Teaming up with a forensic scientist and a police captain, he hunts his exiled senior brother—a master of forbidden blood puppetry—into an ancient underground city to recover the Spirit-Sealing Ink Marker, before Japanese invaders descend on Fog City. A tale of brotherhood, betrayal, and redemption.
