A serial demon nicknamed "Blitz" appeared in the city. He killed several police officers in a haze, but his murder weapon was only a hammer. No one knows his whereabouts, and his sophisticated modus operandi makes it difficult for the police to solve the case. Arrogant, before and after each crime, he will report the details of the crime section with Deng Lopu (David Morris David Morrissey), who is in charge of the crime section of a newspaper, so as to pursue the attention of the society. Dunlop did not notify the police for his fame, which dashed the police's plan to block the information every time, so it was noticed by the police. The impulsive and fiery policeman Brent (Jason Statham Jason Statham) has been repeatedly complained and published in the newspaper because of his strong sense of justice, which annoys his boss. This time, Brent was ordered to track down the murderer, and in the face of the presumptuous provocation of the murderer, he decided to rely on his own hands to do justice for the society.
