Insanity! Young love could be so beautiful if jealousy and annoying ex-boyfriends, like Franziskas' Jonas, didn't come around the corner. Lukas is once again not quite as confident as he would like to be. With Karl, things seem to be going better, at least in love, perhaps because the object of his desire this time is not Tilia. And Otto tries to win back his ex-wife Xenia, but events from the past cannot simply be joked out of the world. And Conny realizes how much she distrusts her fiancé Willi and decides to put him to the test. And that has more unpleasant consequences than she ever imagined.
