Aykut moves to a new private school in the middle of the year with his father, who is the principal. There are two separate groups between girls and boys at the school, which Aykut’s father Nurettin tries to keep in line. The girls’ group is ‘Adab-ı Muaşeret’ and the boys’ group is ‘Mokokolar’. Groups where not everyone is accepted are feuding mischievously among each other. A love affair begins between Aykut and Zeynep, the leader of ‘Adab-ı Muaşeret’, but they both have reasons to keep this love secret.
