London, England. The year is 1995. After a string of murders, the police suspect a serial killer. Detective Eric is assigned to solve the case, and receives the help of Emelia, a teenage girl, whom he previously saved from a house fire. She happens to be resourceful regarding such matters because of her obsession with detective novels. The criminal always leaves his signature at the scene of the crime: a drawing of a black cat is always found on the left cheek of the victims, along with some mutilations of the corpses. It is as if he were leaving a message, which Emelia interprets as, "I don't hear, I don't see, I don't speak." Unexpected events take place after the criminal dubbed 'The Black Cat' appeared with a completely different killing method for his new victims, leaving the corpses in a similar place, and here the events begin and the detective's attempt to solve the mystery with the help of the young teenager.
