At first, the soul of the dead Nick Cruz thought all this was a joke, but it was not until he saw all kinds of demons and ghosts that he was convinced that the underworld police station was real. The police department assigned Cruz a partner-needless to say, the rookie who led the rookie was the old Jianghu, Roy Ball. The old and the young began to cooperate, and they were ordered to go to the world to capture a few monsters that ran out of the underworld. These monsters usually dress up like ordinary people, but when they encounter old rivers and lakes like Bauer, they reveal their nature.
Under the cover of his new identity, Bauer's new image in the world is a young girl, and Cruz has become a Chinese old man-they are carrying out their own actions in the world. They have a common goal, but Cruz has one more goal: he wants to use his performance and strength to win the respect of Bauer.
