Castle Einstein

Finally back at Einstein! But Mr. Hauser is waiting there and is turning the first day after the holidays into a competition. The kids are not going to put up with that.

Rebellion against Hauser! That is why the Einsteiners have moved into the forest. But when Mr. Chung discovers the camp, it is questionable whether everyone has only one goal.

Frida's persistence forces Mrs. Holopainen to introduce a new module. Marlon feels left behind and Maxi feels bullied by Luna in sports.

Luna and Sami's relationship is put to the test. While Massuda tries to get Frida to talk by any means possible, Mr. Chung is bribed.

Joshua is extremely annoyed with Tahmina. And while Ava commits a terrible theft, Ruby and Chiara simply cannot take themselves seriously.

Massuda has a guilty conscience and feels responsible for Mr. Hauser. Chiara and Ruby simply can't get along and Ava confesses to her theft.

Hugo's big moment has come: Massuda wants his story on her podcast! Luna struggles with jealousy, and Ava realizes there's more to Elly.

The survival module starts, but Malik prefers to stay at the boarding school. Marlon is on the trail of Hugo's story, and Ruby is afraid of losing Chiara.

The students have arrived at camp. After the shock of the empty forest clearing has passed, the first challenge begins: building a shelter! But instead of sticking together, the Einsteiners begin to argue. Are they all for Einstein? In the forest, this seems to be forgotten. Simon has also been forgotten. Leon encounters Massuda and the clothing carousel. The two celebrate, and he forgets that he was supposed to be meeting his best friend.

The second day in the forest: The Einsteiners have to find food and make a fire. Mikka is left alone in the camp, his mind still on a scary story about the witch from Haarberg. Suddenly, he wakes up. What's that rustling? Sami is spending time with Maxi and Tahmina. He completely oversleeps during training with Luna. Frida disagrees with Hauser's assessments in gym class. There has to be more fairness!

Marlon constantly thinks about Nesrin, but Hugo also doesn't leave him alone, until Marlon and Karl suddenly find solid evidence that should convict Hugo. Joshua has promised Malik that he will take care of his Survival-X village. He predicts that Malik won't recognize his village. Simon tries everything to get closer to Leon again.

When Malik receives a secret message from Joshua, he can't take it anymore. Something's wrong! He has to go back to the boarding school and check what's happening in his game. But Malik doesn't get very far. Luna misses her time with Sami and wants to impress him with a new best friend. Joshua's plan to push Malik's Survival X Village doesn't work. Even worse: his fellow players are deserting him.

Sami meets the others while chilling, but can't relax after the huge fight with Luna. Does Luna really think he kissed someone else? Maxi, of all people, wants to save the day. Ruby has a surprise for Chiara, but it ends with Ruby being locked in the closet. After the survival camp, Ava is looking forward to a nice bike ride with Lilly. But where is her companion?

The second survival camp is starting. Hugo is there too. As a professional, he's immediately given his first task: building a water filter. However, he reaches his limits and has to confess to Karl why! Massuda is late for the first lesson. When she enters the classroom, she's greeted with insults, and her guilty conscience toward Mr. Hauser returns. Is she in the wrong class? Only Ava can catch up on her bike ride in peace.

Strange things are happening at camp: First, Frida's carving knife disappears, and then Karl's hat. And suddenly, a sinister symbol appears that haunts Karl. Is the camp being sabotaged? Marlon misses Nesrin so much that Sami and Luna organize an online dinner for him. Chess is planned for the board game module.

Elly keeps winning against Mr. Zech at chess. But he can't believe this and challenges her again and again, so she finally hides from him. Elly's interest is in someone else, not the game, anyway. Leon tries out different pronouns with the help of Massuda and Simon.

Leon doesn't want to disappoint Charlotte and tries to get tickets to her favorite band's sold-out concert. Easier said than done. A diversionary tactic is needed, with Massuda and Simon doing their best to support Leon. Even though the two are actually taking law lessons with Mr. Berger.

A terrible accident occurs at the camp, prompting Marlon to step in as a detective. Together with Nesrin, he investigates how it happened. They both find a crucial piece of evidence that convicts the culprit! The survival module is on hold, and Hugo is in the Johannes Thal Hospital with a broken arm.

Mikka is making music with Ruby when Amani suddenly arrives and wants to join in. Tahmi shows with her homemade "Tahmimisu" that everyone accepts Hugo's apology. Frida is certain, and Marlon's verdict is also final: Joshua is guilty! All the evidence speaks against him! But before Marlon can make his article public, Joshua must apologize to everyone.

After Chiara speaks with Reena on the phone, she begins to have doubts about her future. What will she do after Einstein? Together with Hugo, she immerses herself in a fantasy world of possible careers. Joshua is put on trial. The students assign roles: Massuda becomes a judge and Ava a lawyer. Elly doesn't like that at all.
