In the first episode, Grete and her family are moving from Hamburg to the Black Forest. No sooner have they arrived than the first difficulties arise, because the Hansens can't get into their new house...

Nico arrives back at Inga's on crutches, but luckily with no broken bones. At the doctor's orders, he needs to take painkillers, use salve, and most importantly, stay off his leg – something he finds difficult to do.

So where is Yara? Lisa's father asks Nico and Yara's friends a series of questions. Then they find some evidence that Yara might be in Switzerland. But why?

When Nico comes home, Inge offers him some of her late husband's clothing. Just as he has put on something elegant, Selma stops by.

Selma and Lisa talk on the phone. Lisa is still on vacation and enjoying great weather. While they are talking, Selma makes an exciting discovery.

The story of Nico's lost bag continues: two men find it in the street and check if there's anything useful inside.

Here we see what happened to Nico's bag, but get no answers yet as to where it ended up.

Lisa runs off to a job interview, prompting a discussion about careers. It turns out both Max and Tarek have worked and trained in other professions.

Lisa arrives at home to find Nico and Emma eating dinner. In a flashback, Emma reviews her plans for the week.

Lisa reviews Emma's schedule with Nico so that he will be prepared for his duties as a babysitter.

Lisa's colleague is ill and can't teach her class. Lisa would like to help out, but needs to find someone to babysit for Emma first.

The next potential roommate is obviously too fussy for Lisa's apartment.

The next candidate to take over Nawin's room also fails to make a good impression on the group.

A first potential new housemate comes to look at the room and takes a tour of the group's Wohngemeinschaft (shared apartment).

Nico can't stay in the shared apartment anymore, but Lisa gives him some ideas where he might possibly stay.
