The narrative strength of the series lies in its ensemble cast of five students: Can, Melek, Zülfikar, Mert, and Aylin. Each student carries a burden—poverty, family dysfunction, or criminal temptation.

At the heart of the series is Sadi Payaslı, portrayed by Ertan Saban. Sadi is a former man of the underworld who, after a life-altering decision to cooperate with the police, is placed in a witness protection program. Rebranded as a geography teacher, he is assigned to Karabayır High School.
