Cem, a successful motorcycle racer, is living a happy life with his wife Özlem and son Efe when suddenly everything is turned upside down. When he comes home from work, no one answers the door. The day before, he had a brief argument with his wife over the motorcycle. Thinking that his wife Özlem had gone to his mother's house, Cem goes to his mother's house, but his mother closes the door in his face, saying she doesn't recognize him. After spending the night on the street, Cem goes to his wife's workplace the next day and sees Özlem holding hands with another man. In response to this situation, Cem beats up the man next to Özlem, and Cem is taken to the police station. After giving his statement at the police station, Cem is sent to a mental hospital.
