Nina's first day at school really isn't going so well, but she rejects Emma's help and doesn't tell her father what happened. Meanwhile, Emma's dad settles into their new apartment.

When it becomes clear that his nephew Henri can't stay on his boat, Jan brings him to Emma's father, Hannes. Emma, however, is not happy to find that a guest has taken over her space in the attic – which also serves as the Peppercorn headquarters.

After a second wallet is stolen, everyone becomes even more suspicious of Nina. Max is still convinced that she didn't steal anything, and while he and Emma are in math class, Henri stands watch outside the gym.

Henri and Emma finally chase down the thief – and prove that Nina didn't steal any of the wallets.

After the Peppercorns wrap up the case of the stolen wallets, Max sets off on his bike to his grandmother's food truck – and has an unfortunate encounter along the way.

Max confronts Dragan about the money Dragan is demanding from Max's grandmother... then finds himself in a bad situation.

Emma is determined to help Max, who is being blackmailed by a drug dealer. Nina continues to claim that she doesn't need any friends and doesn't want to join the Peppercorns. Meanwhile, a student has a bad reaction to the happy pills...

After Anna is taken to the hospital, Nina goes to find Emma, only to learn that Emma's in Sankt Pauli trying to trace the origins of the drugs.

Having broken into Dragan's place, Emma and Nina learn that he is using their classmates to push drugs at their school and others. Suddenly, the dealers come back to their hideout – and the girls are trapped!

If the drug dealer Dragan finds out that the Peppercorns are on his trail, he’ll surely make trouble for them. Fortunately, Emma, Nina, and Max are able hatch a plan to get Dragan arrested before it's too late.

Emma, Henri, and Max want Nina to join the Peppercorns, but she's very reluctant to engage with them. Emma picks Nina as her partner for a photo project, hoping that she’ll find out more about her. But then something unexpected happens…

Emma and Nina follow Milla, the girl who ran off with their camera, and confront her in her messy apartment, where she lives with her sick mother. Although they manage to get the camera back, Nina’s relief is clouded by the fact that she feels sorry for Milla.

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.
