Behzat Ç. is a detective in the Ankara Police Department. He is the head of a unit of six people: Harun, Hayalet, Akbaba, Selim, Cevdet and Eda. They usually work together with the public prosecuter Esra. They chase criminals with perseverance and solve murders and other crimes that occur in Ankara. Behzat Ç. graduated from the Police academy in 1985. He does not care much about his superiors -not even laws in some cases; he only follows his inner conscience. This often brings him troubles: Even though he graduated from the Police Academy many years ago, he is still stuck in the same position for years unlike his colleagues who are at the peak of their career, because of numerous suspensions and reprimands he got. After an unsuccessful marriage, he is not confident with women. The only woman he seems to care about is his daughter Berna.
