The demolition is prevented at the last moment. The police take Marc, Till, Antonia and Heike to the police station and inform their parents. The four of them forget the cash box with the party proceeds in the ruin. Till is horrified when he learns that the building has been blown up and the money is lost. His father condemns him to work off the amount he has taken from the cash register in the bakery. At the precinct, Wolfgang and Joachim fall together by the ears over the question of who is to blame for the unfortunate party. Joachim is so angry with Marc that he announces that he will send his wayward son to boarding school. Alexander does not dare to confess his deep feelings to Corinna and tell her how much he would like to sleep with her. Seeking advice, he turns to Armin, who willingly gives him tutoring. Just as Alexander repeats a declaration of love to him, Aylin stands in the door and of course takes the situation wrongly.
