Nina gets in trouble with her father when he finds out she was the one who damaged the headmistress’s car. Meanwhile, Leila’s ex-partner Mark shows up to help Milla clean their filthy apartment.

Milla, Leila, and Mark have cleaned the place up for Ms. Wiedemann's visit. Is everything going to go as planned?

Milla thanks Emma for not exposing the truth during the youth welfare officer’s visit to the apartment. Meanwhile, Max and Henri set off to visit Nina’s old school — and come closer to cracking her secret.

The Peppercorns finally find out why Nina was bullied at her old school. Meanwhile, Emma has a guilty conscience about having lied on Milla’s behalf — did she do the right thing? Jan heads over the next day to try to sort things out with Milla and her mother in person.

Jan finds Milla’s mother just in time, and makes sure that she is taken to hospital. But where’s Milla? Emma and Nina go looking for her. With everything resolved, it’s time for the new team of Peppercorns to take the oath.

Nina is acting quite strange... Could it be that she's in love? Meanwhile, the donation box has been stolen from the school administrator’s office!

Matteo is caught by Mr. Sass with the stolen donation box, but claims that it was given to him by… a tiger? With Mr. Sass threatening to punish Matteo for a theft he may not have committed, the Peppercorns get to work on cracking the case.

Franzi confronts her father, Nina has trouble with Max, and the Pellicanos discuss the accusation made against Matteo – while Mr. Sass threatens to call the youth welfare office.

After the Peppercorns conclude that Franzi must have been stealing from their classmates, Max confronts her in the boxing gym. But there's a lot about Franzi that he doesn't know.

Franzi tells Nina that she was the one who stole the cash box. But Nina doesn’t believe her – so Franzi finally tells Nina the truth about her dad, who’s promised to never steal again. The Peppercorns decide to put him to the test.

When Max is at a boxing match with Nina, he gets a call from Emma: Eddie has run away! Should they call the police? Max has another idea…

As Mr. Sass apologizes to Matteo for accusing him of stealing the cash box, Nina announces that the real culprit has turned himself in. Grandpa announces that he’ll be visiting from Italy earlier than expected, and Nina’s dad fends off a secret admirer.

Maria, Nina, and Matteo are horrified to find that someone has completely destroyed the surprise they put together for Antonio. Luckily, the Peppercorns are on the case.

Emma discovers that hydrangeas are being cut off all over the neighborhood. Meanwhile, Jackie is heartbroken over being rejected by Nina’s dad. But that’s not her biggest problem right now…

Nina's grandpa arrives in good spirits. He’s even brought along Nina's cousin Marcello, who Max still thinks is Nina's ex-boyfriend! Meanwhile, Emma watches with interest as Jackie gets into a heated argument on the phone with her irresponsible brother, Marvin.
