Cem and his five best friends have been a close-knit community since childhood. For him, they are his true family. But Cem is changing. He becomes more brutal and harder, threatens his friends and terrifies their relatives. After a stay in a psychiatric ward, he does not take the prescribed medication. Threats of violence and aggressive outbursts become more and more frequent. What happens inside him remains incomprehensible to the outside world. Only with Lara is he different. His world is alien to her, which is perhaps the reason why he likes her so much. Cem's friends are torn between their loyalty to their childhood friend and their fear of the ever-increasing danger he poses. At some point, this fear becomes so great that it is unleashed in a brutal act of vigilante justice.

Criminal investigator Philip Nabrow is tasked with solving the murder of two police officers. When the case starts to focus on a boxing club, his daughter Elisa, who works in the drug squad, also becomes involved. Cooperation between father and daughter proves difficult, as Nabrow has a secret that he wants to hide, and not just from Elisa.
