In 2026, the Year of the Fire Horse, strange anomalies begin to multiply in a county town. Chen Mo, a solitary police officer, puts on a pair of copper-framed glasses that let him see "the truth". Armed with talisman bullets, he becomes the last field agent fighting the supernatural. Reflections inside walls, bloody writing in case files, a "door" beneath an old locust tree... He soon discovers that he has been chosen as a "Night Watcher". Every Year of the Fire Horse, someone must become the lock itself, sealing the fissure that connects to beings beyond comprehension.
His predecessor became a pile of bones at the bottom of a well, while whispers from behind the door have continued for sixty years. Chen Mo refuses to stay silent and sacrifice himself. Instead, he chooses to devour the "anomalies" and turn himself into a furnace, struggling to survive on the brink of becoming inhuman as he searches for the key to ending the cycle. Now a dark golden flame is branded in his right eye, and burn scars crawl across his arm. He roams the city's shadows, evading the "cleaners" and fighting the backlash within him. In a ghost market on a rainy night, he meets a girl who can see "blurry shadows" and the relic in her arms that may hold the original secret...
The Year of the Fire Horse is not over, and the door is about to give way. He is an ember walking along the blade's edge, the last Night Watcher searching for a glimmer of light in the endless night.
