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.

Kutay and Yusuf are two friends who work at a gas station. One evening, they decide to steal a night out on the town, but since they have no money, they take a considerable amount of cash from the gas station's cash register and head to the bars of Beyoğlu! It doesn't take long for the station owner, Ethem Bey, to notice the money missing from the cash register. Kutay and Yusuf, who are trying to find a way to replace the money, are fired when they can’t manage it. But as they leave, they take the car left at the station with them! The friends, whose paths cross with Osman Nuri and Selman, find themselves caught up in an inescapable mafia and hostage-taking/kidnapping adventure!
