The second film begins in early April with Tarkan's return. He wanted to go back to Hamburg with the stolen 800 marks. The next night, Christian is gone. The group travels on to Lisbon to start investigating Christian's whereabouts. At the same time, school starts again. Christian has once again been caught by the police stealing a car. Three days later, he is back with the group. An educational attempt at clarification begins: Why did he run away? Why did he steal? Why the cars?
