Everyone is happy to start the new school year with the famous wonder waffles from the Freytag sisters. But when Flora posts a funny video of the action on the Internet, her sister Finja of all people becomes the victim of hateful comments. This bad start comes about: According to Einstein's rules, couples have to sleep in separate rooms, including Leni and her friend Cäcilia. Unaffected by all this, newcomer Bela lets it rip, musically ...

Ex-Einsteiner Pia Pigalke appears at the Einstein to head the new Internet & Security module. The strange thing about it: The teachers don't know anything, and Finja as a victim of bullying is not allowed to participate. Meanwhile, Hermann is wondering what Jonah is planning, and of all people, Gustav, his new roommate, seems to know the answer.

Reena messes with Ms. Pigalke: She does not find their methods correct. Even outside of the small group of chosen ones who are allowed to participate, the module causes annoyance: Why are they allowed and we are not? Sibel not only has to deal with the fact that the border runs exactly between her and Pawel, as a mentor she also has to take care of Joyce.

The selected modules do not make all Einsteiners happy: Hermann has to share a herb with Gustav, of all people, Anton tries his luck in the sprint relay because of his father, and Rosa would so much like to be an insider on Ms. Pigalke's module.

The endeavors of some Einsteiners have a different outcome than expected: Reena goes far too far in the Internet & Security module and thus causes trouble, Badu cannot assert himself as a relay trainer for one day, and the day Rosa and Anton spend together ends differently than expected.

The forest days are not going as planned. Ms. Stocker and Chiara miss the bus and have to follow them by taxi, and Sibel and Pawel never come back from collecting wood. Rosa, Viktor and Bela go into hiding at the boarding school.

Hermann, Gustav and Chiara are stuck together: quarantine after an unexplained rash. In the Internet & Security module, Ms. Pigalke lets Moritz and Flora compete in the digital election campaign for the office of head boy. Meanwhile, Mr. Hauser tries to find his way around in the unfamiliar role of a father.

Finja and Paul are tracking down a strange symbol. You are on the right track, but you haven't made it to your destination yet. Reena works as Flora's campaign manager. The guns it brings out force Moritz to detonate the next stage. Rosa loses interest in speed skating and now has to decide on a new focus.

The new school year on Einstein begins with a colorful bang. The new students in particular are good for a surprise.

On the first day of school everyone asked themselves: What will the future or the learning module “Future bring? Cäcilia is skeptical and Moritz gets lost in daydreams.

Internship day at Einstein: While Moritz appears underdressed, Martha works up a sweat and Carolin takes her fate in both hands.

Jona and Hermann dedicate themselves to their favorite prank victim. Are they really getting through with their pranks?

Hauser puts the sporting skills of his students to the test and Flora the patience of her sisters.

Jona has a new experience to master and, with Hermann and Chung, two overwhelmed men at her side.

The Einstein boys don't have it easy - Viktor has a date, Hermann doubts his masculinity and Moritz has bad suspicions.

Since Till has been back on the Einstein, he's been acting strangely - will someone crack his secret?

Away from Einstein, Flora finds a retreat that has an animal task in store for her.

The Einstein crackles. While some are still practicing, others already know.

Hermann and Pit are on fire for their new project. What's going to go wrong there? Carolin has some concerns because she faces a difficult choice. Anton, on the other hand, makes a quick decision that has unforeseen consequences.

Hermann plagues his guilty conscience and he tries to reverse his act as best he can. Hauser entrusts Rike and Anton with undercover investigations. Both quickly discover that the Einsteiner's secrets are not that easy to crack. Who is hiding something?

The entire Schloss Einstein boarding school pulls together when it comes to supporting a teacher. X-Press editor Moritz is also following a hot lead.

Two Einsteiners have a secret. But how long can you keep it to yourself? Miesbach's art project #nofake brings unimagined truths to light. Martha and Sibel also surprise everyone with a revelation.

Viktor discovers a new talent and Moritz's research finally ends in a surprising success. However, Rosa is facing a difficult sports test.

Cecilia is planning a sweet surprise. Rike receives an unexpected message through her tarot cards and sprint ace Viktor sets new priorities. What is it all about?

Rike and Badu can't believe what's going on with Viktor and want to bring him to his senses with their very individual methods. X-Press editor Moritz issues a momentous ultimatum.

A great secret is revealed. How will the Einsteiners react? While Viktor has completely different worries, Jonah succeeds in a stroke of genius when it comes to Pranks.

Finja's magic trick just works too well. Pit is pissed off. Martha, on the other hand, wants to look forward to the upcoming weekend, but she doesn't really want to be in a good mood. Flora and pink make a great discovery.

Flora demands commitment from the Einsteiners and Rosa takes on a brave task. Pavel would like to celebrate the anniversary with Sibel in a special way. But why is she taking flight?

The intermediate exams on the Einstein are coming up when suddenly a much more important task calls for them. Above all, Pawel wants to be his man. Anton also tries to do his best.

After the big action, everyone is wondering if a party is really the right sign? Rosa has her doubts because she is shown the harsh reality. Even a new student would have imagined life with Einstein to be easier.

The half year is drawing to a close. But that doesn't mean it's getting any easier. You could almost say it's getting more complicated. Finja confides a well-kept secret to her older sister Flora. Till gives Pawel tips about Sibel, but is that really his expertise? Sibel tries to stay calm, but is distracted by Martha.

Anton and Rosa each have to clarify an important matter, while there is nothing left to clarify for Jona and Hermann.

Individual Einsteiners are faced with an almost insurmountable task. But it is not for nothing that it is called “One for all and all for Einstein”!

Einstein is upside down. Because the merger with the unloved sports boarding school is a done deal - it only helps to close your eyes and through! Martha & Co. promise Director Chung to behave. It quickly turns out that it won't be that easy. The cool athlete gang around Till, Nick and Timo welcomes the Einsteiners with little joy.

The arrival at the new boarding school is complete. But nothing more. The athletes don't even see a share of their boarding school. Prima ballerina Caro in particular is annoyed when everyone wants to take over her ballet hall. New rules also apply in school. Einsteiner and athletes should work together, but both sides only want one thing: get rid of the others!

Martha arms herself with hard guns, because she doesn't want the athletes to dance around her nose. You live here now too. But are all Einsteiners on your side?

The 400m relay of the sports high school is under pressure, the times are not right. Are you lacking focus? Viktor definitely not, he is running the best times. Reporter Rike thinks he must be interested in something other than sport!

Casimir is finally coming back. Martha is full of anticipation and wants to plan a surprise for her boyfriend with Nele. Girl stuff isn't for Martha at all, is it?

Einsteiner or athlete? There is no in between, think both Nele and Nick and heat up the atmosphere. But is every student really only on one side when the other seems much more exciting?

A new learning module starts at school with the project day gravity. Nele goes to great lengths while the teachers enjoy their team day to an unimaginable amount. Everything seems fine - until the next morning when the most important things about Einstein are missing.

Einstein is very excited. There has not been something like that before. Was it a brazen theft or an accident? Einsteiner and athletes blame each other. Director Stocker and Director Chung face a tough decision. At the same time, Caro is also struggling with a decision regarding her upcoming ballet exam. Einsteiner or athlete? There is no in between, think both Martha and Till and heat up the mood. But is every student really only on one side when the other seems much more exciting?

Athlete Nick and his mentor Kasimir are faced with a difficult task. Together they should master their physics lecture. A team of athletes and Einsteiners, can that go well? There is also tension in the girls' room. Olivia and prima ballerina Caro are looking forward to their important exam.

Who is responsible for all the mess? Everyone is wondering that. Each party looks to the other to blame. Rike, Hermann and Moritz finally want to bring peace to the Einstein again and forge a plan.

Martha is planning a big coup and prank queen Jona really wants to be there. You can't do that from home. But how is she supposed to convince her dad to move to boarding school right now?

Showdown between TNT boss Till and Martha: is peace finally coming back to boarding school? The rest of the students are slowly getting too stupid. After all, there are more important things in life: an unexpected letter for Olivia doesn't just make Rosa curious.

You have to celebrate the festivals as they come, says Rosa and wants to get Einsteiner and athletes to agree to a ceasefire. The little optimist does not allow any arguing and prepares Einstein for the party of the year.

What happened? Why was the ambulance at the school when the students arrived in the morning? Nobody knows. Really none? The directors anxiously await news from Dr. Ruhland (guest role Gunda Ebert).

After the blatant incident, athletes and Einsteiners get together and prepare a surprise. Ms. Stocker and Mr. Chung also hope that everything will be fine now. But school councilor Dr. Berger has his own plans and completely upset the positive mood.

Cäcilia is supposed to prove what she can do on her career and a dream comes true for Martha and Till. The schools will be separated again! The other students are shocked. How did they let it get this far?

While Rike and Rosa are feverishly looking for a solution to the whole mess, Cäcilia and Sibel have completely different problems. And Pavel is sitting between the chairs.

Nele and Martha are actually best friends. Actually! They don't understand each other anymore. Schiller and Hauser show their students new methods of dealing with differences of opinion.

It's a done deal, Einstein must be saved! But how can you plan an exciting and at the same time convincing campaign around school board member Dr. To dissuade Berger from separating schools?

While she makes every effort to stamp the joint project out of the ground, the otherwise so level-headed Nele has to take care of her misstep. She screwed up a lot and Till went one better. Unexpected help rushes out.

There are no impossible missions for the dream team Hermann and Jona. With the support of Pit, they create the best conditions for the secret action Save the School.

The students give everything to convince their teachers. But are they really all pulling together? How do Mr. Chung and Ms. Stocker react, can they respond to the wishes of the students?

Not only the directors, but also Dr. Berger is a tough guy. A really good plan is needed. In addition, the Central German Championships are in the individual run and everyone is betting on Viktor. Can he live up to these high expectations?

Preparations for Plan C are in full swing. What exactly Einsteiner and the athlete plan together remains a secret, until suddenly everything has to go very quickly.

After all the mess, Pit has a surprise. But will he really be happy about it?

Everyone - athletes and Einsteiners - prove that they belong together. Nobody is lost! True to the motto: One for all and all for Einstein!

Martha, Sarah and Nele are ready: if Frau Schiller wants war, she can have it! The new school year begins with a shock for Martha, Sarah and Nele: Ms. Schiller has distributed them to different rooms. That's of course not okay!
