Under the shadow of the city, a cruel performance competition between living people and ghosts is quietly staged. The performance indicators of July and a half are both a countdown to the soul and a crack in the balance of yin and yang. The rookie agent was forced to get involved in this fight, but found that behind every resentful spirit was a carefully designed trap. When collecting souls turns into a conspiracy to increase performance, he must join forces with a rebellious ghost and a mysterious guide to uncover the truth behind the collapse of the system - and the key to repairing the cracks is actually hidden in the souls of the relatives he lost in the first place.
