Love chaos at the SISTAR: Sabrina wants to hide her affair with ex-Waldorf student Casper so as not to jeopardize her reputation as a neighborhood slut. Penelope ends up in bed with director Jens Dietrich while intoxicated with raki, and Ulla spends a night of love with policeman Hermann. Max tries to confess his love to Ratte, but fails because of an allergy to animal hair, and Üwele breaks up with Kathrin because he has feelings for Tömle just as Kathrin does. Meanwhile, Hermann finds out that Ulla is the head of Operation Raufaser, a Weddinger underground movement against luxury renovations, while Ulla and Penelope both end up in Ahmed's kebab shop on her fortieth birthday.
