Cem and his five best friends have been a close-knit group since childhood. In fact, Cem regards the others as his true family. But he is changing: becoming tougher and more brutal, threatening his friends and frightening their relatives. After a stay in a psychiatric hospital, Cem fails to take his prescribed medication. His threats of violence and aggressive outbursts grow increasingly common. What is going on inside him remains incomprehensible to the outside world. It is only around Lara that he behaves differently. Cem’s world is alien to her, maybe that’s why he likes her so much. Cem’s mates are torn between loyalty to their childhood friend and fear of the ever-increasing danger he poses. At some point, this fear grows so great that it erupts into an act of brutal vigilantism.
