Bizarre murders occur one after another in the city, and pale golden ancient runes appear around the victims. The circumstances of their death are exactly the same as the "Star Curse" recorded in ancient books.
Gu Shiyan, the calm and decisive criminal investigation captain, meets Shen Zhiyan, a mysterious scholar who comes with a map of the stars - the former possesses modern criminal investigation tools, and the latter is well versed in the mysteries of ancient secret spells. Two completely different paths of investigation intersect due to the common pursuit of the truth.
Under the ancient city shrouded in mist, taboo rituals that have been sealed for thousands of years, star track codes that hide murderous intentions, and bloody promises that span time and space gradually emerge. Every time a rune appears, it is accompanied by a deeper conspiracy; every time the stars shift, it heralds a fatal crisis. They not only have to solve the ancient mystery behind the secret curse, resist the crazy pursuit of the forces in the dark, but also face the abyss that they are unwilling to touch in each other's past.
When the trajectory of the stars coincides with the blood runes, and when the good and evil of human nature confront each other in the darkness, is this exploration with life as a bet a reincarnation of fate, or the ultimate counterattack of justice against evil? The two walked side by side on the edge of the abyss, using trust and courage to fight against the invisible curse, just to let the truth break through the darkness and echo in the world under the witness of the stars.
