Nesrin wants to start the new school year with an epic prank and immediately sets his sights on the future competition, but Annika has other plans. Io and Joyce are no help either. They forgot Ms. Miesbach's holiday homework and have to improvise at the last minute - no one should know what you actually did during the holidays. Meanwhile, Julia and Colin are struggling with their first challenge.

Joel wants to assemble the perfect team for the future competition, but none can live up to his standard - except for Mikka and Casper, who brush Joel off. They prefer to work in pairs. While Casper is looking for an idea, Mikka is quickly distracted. Also Julia isn't very enthusiastic when Ava "borrows" her old bike without being asked.

Fabienne is extremely annoyed: Since Massuda has been living in her room, chaos has reigned and the word "demolition party" has all alarm bells ringing for Fabienne. Meanwhile, Joyce forces Noah into a karate match, but he doesn't take her seriously. Can Joyce win this fight? Meanwhile, Reena struggles with her long-distance relationship with Gustav. Chiara's well-intentioned distraction attempts do not inspire him.

Sport is over for Leon for the time being. Why is a mystery. Since the future competition started, he's had other things on his mind anyway, so maybe taking part is a good idea after all. Mikka needs snacks for good ideas. Casper wants to get him that. And Marlon? He overslept enrolling in a new module. Now Mr. Hauser's forest run module threatens him. Will he come out again?

Joel is certain: Noah has a secret! Why else would he stay out all night, climb through windows and even skip class. Colin also notices this behavior. What do you think Noah is hiding? Marlon is relieved not to have ended up in the forest run module. But the new role as editor-in-chief demands more from him than expected. And Julia has to give a presentation with Ava of all people. Can they bury their hatchet?

Reena is frustrated. First she is transferred, then Massuda declares her approach to the clothes carousel project with Chiara to be unsuitable. Chiara already has the saving idea, but first she has to lure Reena out of her comfort zone. Noah has to leave too and unexpectedly finds allies. Leon can hardly wait to see Io again and promptly makes a mistake.

Lightning storm at the sports boarding school Schloss Einstein. New photos will be taken for the website. Especially between Fabienne and Massuda there is thunder and in the end not only Fabienne's pride is hurt. After a foiled prank, Nesrin and Annika plan their slimy revenge while Marlon prepares an interview for the Rocket Xpress. But Dr. Berger doesn't stop talking and thwarts Marlon.

Colin is frustrated, his future project is at a dead end. Luckily he finds an open ear with Noah. But then something happens that has serious consequences. Meanwhile, Joel pursues new business goals and is put to the test by Nesrin and Annika during the night. Meanwhile, Ava has her own plans and Ms. Schiller has her hands full again.

Noah worries about Freddy the dog's future and blames Colin. As an apology, Colin gets tickets to a horror movie premiere thanks to Ava. Julia is dying to know who Ava's contact is in the film scene, but she keeps quiet. Until her contact suddenly shows up personally at the Einstein. Io tries to convince Joyce to join Leon's competition team, but didn't expect Joyce to go it alone.

Massuda and Marlon investigate a suspected case of sabotage and make a shocking discovery. Joyce wants to prove to Io that together they can do anything. Can Sirius help her? Meanwhile, Reena wants to find common ground with Gustav again. But instead of telling him about her actual problems, Reena quickly invents a new "harmless" problem that quickly becomes her undoing.

What do a man-eating chair and multiple explosions have in common? Julia initially doubts the connection, but Noah hopes it's enough for an apology to Colin. Marlon and Massuda share Ms. Amani's secret in the editorial office. Massuda would like to write a sensational article right away, but Chiara and Sirius decide instead how they can help.

The prototype presentation is imminent. Joyce and Io have made a breakthrough, but first Joyce has yet to fight a duel with Noah. Meanwhile, Nesrin is anything but convinced of Joel's concept of a Prank Inc., but Annika disagrees. And they already have their first order. Massuda goes through a veritable metamorphosis for her parents' visit.

Prototype day: Io gives it her all, but mishaps follow mishaps and Leon's rescue only seems to make things worse. Reena is no better. An essential part of her presentation is missing and Gustav has apparently forgotten her. Joel and Colin's project is a success. But Noah's short film seems to make sure of that. Joel can't let that sit on him.

Reena is stressed: Gustav doesn't seem to have heard a blatant message and she wants to do everything to keep it that way. On the other hand, Mikka would rather be honest when he accidentally crushes Sirius' fresh harvest in the school garden. But Casper thinks it's nonsense to take the blame for it. Nobody saw it. Annika and Nesrin may find a way to reconcile over a mysterious find.

Fabienne is not enthusiastic when Mr. Hauser organizes a badminton tournament instead of heptathlon training the day before the big competition qualification. Ironically, she chooses Massuda as a partner. Not exactly a dream team - or maybe? Chiara wonders how she can help Ms. Amani and unintentionally ends up in her office hours. Casper neglects his school duties to help Mikka get a great grade.

Julia is stunned that she has to go to an audition to star in Noah's horror film. To prove she's a born actress, she surprises Noah with a dramatic performance out of nowhere and is bitterly disappointed. Marlon has a hard time making an announcement to Sirius in the Rocket XPress and Joyce tries to convince Noah of her brilliant idea, but her performance stuns everyone.

Ava's bike, Lilly, is stolen and Ava is determined to find it back. As a gamer, defeating the thief and freeing Lilly shouldn't be a problem. Reena fears Gustav's farewell. What will happen to them in the future? One thing is clear, there is no avoiding a conversation. Joyce doesn't see that she did anything wrong with her performance and realizes too late that she hurt Io badly.

The last training before the state finals in the heptathlon is coming up. Massuda promises to do her best, but a well-planned prank thwarts her plans. Nesrin and Annika are pros. But they're fed up with Joel constantly posing as the boss. Chiara keeps collecting problems until Sirius finds out and asks her the crucial question: Is it okay to "steal" someone else's problems?

Io, Leon and Joyce's project hits a dead end and while Joyce distracts Ms. Schiller, Io and Leon work the night shift at the boarding school. Fabienne refuses to admit her prank on Massuda, whereupon she launches a counterattack. Marlon also sees a night shift coming up again. Until Joel gives him the idea to make a virtue out of his mistake. Will Sirius and Chiara notice Marlon's double play?

Nesrin and Annika enjoy "prank" holidays until Joel shows them rule 23 from the regulations: There is no such thing as a prank-free time. Nesrin begins to suspect. Casper is jealous that Mikka and Reena get along so well and straddle in between. Julia is desperate: For lack of alternatives, Noah plays the main role in his film himself and that doesn't work. Do they have to write off the film before it's shot?

Joyce suspects bad news when she is summoned to the directorate. But what she finds out there could change her life forever. Casper goes haywire: While other teams celebrate their breakthrough, his team struggles with technical problems. Casper wants to prove himself to everyone, even if it means crossing borders. Colin, on the other hand, just wants to be left alone and "do nothing" with Noah.

Julia thinks she's on cloud nine and desperately needs a reality check. Something is also wrong with Fabienne. Today would have been the state final, but you can't be that depressed. Massuda wants to do something about it and glitter is always supposed to help. Chiara tries unsuccessfully to get rid of her guilty conscience until Sirius gives her a tip - some things you can't run away from.

Noah is abandoned by his team. Free planning for weeks. Only Colin is there for him. But then something happens that throws their friendship completely off track and suddenly both of them can no longer think clearly. Joel needs Colin's help. Someone sabotaged their project. Fabienne challenges Massuda to one last match, and for the first time, it's not all about winning.

Julia wants to risk everything to save her friendship with Ava. She has a plan, but she needs a team. Meanwhile, Marlon calls an emergency editorial meeting and alienates everyone with his Kontroletti speech. Colin's mind is somewhere else because what happened between him and Noah can't let him go. Noah is very similar. Is there more between them than just friendship?

Everyone cheats a bit, Casper is sure of that. That's the only way to win. But this time his words don't seem to convince Mikka. Marlon convinces the editors with an apology. Because he needs their help to uncover unfair behavior in the competition - Sirius was right from the start! Meanwhile, Io and Leon are on cloud nine, until a comment from Joyce causes Io to start questioning everything.

It's finally here, the day of the final future pitch. And Joyce has an important decision to make, too. Io is worried because there is no trace of Leon and suddenly there is an ambulance in front of the Share Space. What happened? With Mikka's worst suspicions confirmed, the teams begin their presentations. The big question remains, who will win the competition? One thing is clear, there will be celebrations at the end.
