Lin Xiao traveled through the world of Hong Kong movies and became a supporting actor, activating the "extreme crime interpretation system". In order to survive, he had to play the role of a gangster and fight against the thugs. As a result, his acting was too realistic and he was wanted in Hong Kong. What's even more troublesome is that the policewoman Shen Qingchi who is responsible for hunting him is known as the police genius, cold and sharp, but she has developed a morbid obsession with Lin Xiao's "true performance". While she was issuing a kill order, she sent a secret message late at night: "You performed very well. Next time you can only perform for me." Lin Xiao walked on the edge of a knife, acting crazily on the edge of black and white, and she was his most dangerous and obsessed audience.
