Strange murders occurred one after another in Linjiang City. The deceased had a strange smile on his face. His heart was taken out but there was no trauma. Ancient symbols were left at the scene, pointing to some kind of religious ceremony. Interpol captain Lin Yi was forced to cooperate with folklore professor Qi Hongyao. This young female scholar has amazing insights into ancient mythology and semiotics, but seems to be hiding more secrets. The five-pointed star pattern at the crime scene is consistent with the "Five Directions Soul Resurrection" ritual recorded in ancient books, implying that someone is destroying the ancient seal and releasing the suppressed power of the evil god. Qi Hongyao is actually a contemporary city god, tasked with guarding the balance of yin and yang. She must help solve the case without revealing her identity, and at the same time track down the real culprit who broke the seal. Lin Yi gradually discovered the supernatural side of the case and established a subtle relationship of trust with Qi Hongyao. The two faced the dual threats from human and supernatural forces together. As the Ghost Festival approaches, the mastermind behind the scenes is about to complete the ritual. Qi Hongyao must make a choice at the critical moment of life and death - whether to stick to his duty to protect mortals, or to sacrifice himself to completely seal the evil god.
