‘AWAKEN, ANGELS OF VENGEANCE! JOIN ME AND HELP ME CLEANSE THIS WORLD!’ Bolesławiec is shaken by the brutal murder of a young woman whose body is found in a remote spot. Particular attention is drawn to the letter ‘R’ carved into her body – the same mark that Roland Zydar, known as the Raptor, left on his victims years ago. Although he has been behind bars for a decade, Detective Inspector Błażej Heller and his partner, Malwina Zygart, suspect that he may have something to do with the crime. They therefore decide to confront him. What they do not know is that the Raptor has been waiting for exactly this. Before long, the killer draws them into a psychological game that proves especially dangerous for Malwina – his biological daughter. The woman who joined the police to break with her difficult past must once again come face to face with the man she has spent her whole life trying to cut herself off from. Meanwhile, more mutilated bodies are discovered in the town. Racing against time, Błażej and Malwina try to establish whether the Raptor really is operating from behind bars, or whether someone has come to believe they can match him. Or perhaps even surpass him.
