In the shadowy realm where ancient folklore bleeds into the modern world, Jackie Chan stars as Pu Songling, a legendary monster-hunter who captures demons to write their stories. His solitary existence is upended when a powerful demon escapes from his manuscript, threatening to unleash chaos. Teaming up with a skeptical policeman, played by Ethan Ruan, and a mysterious woman, Elane Zhong, with her own hidden connection to the supernatural, Pu must navigate the treacherous boundary between the realms of Yin and Yang. This action-packed fantasy, directed by Jia Yan, plunges viewers into a visually stunning battle where ink and magic collide. As loyalties are tested and monstrous secrets are revealed, the hunter becomes entangled in a conflict that questions the very nature of good and evil, forcing him to confront a past he thought was long buried.
