Nevin and her new friends are partying, chatting, and enjoying her homemade cake. Suddenly the doorbell rings—who could it be?

Berlin-based skateboarder Lilly Stoephasius is only 12 years old, but she’s already won a European skating championship in the “Park” discipline – and hopes to attend the Olympic games in Tokyo. Here, she and her dad discuss her everyday skating life and her longer-term goals.

Nevin can't wait to surprise her husband with a cake, but she’s disappointed when she finds out he’s tied up at work and won’t be home until the next day. Then the afternoon brightens when Nevin meets some neighbors in the stairwell and gets invited to a party.

Yuna happens to drop in at the grocery store where Nevin is working. And she’s just in time, since Nevin needs help figuring out the names of the vegetables.

The grocery store where Nevin works is about to open for the day, but she’s having trouble remembering the German names for all the vegetables—and her boss is getting impatient...

Here's a flashback to when Frankfurt Airport was buzzing with activity. The airport opened its doors in celebration of Mother's Day, offering special activities and prizes. Despite strikes at the time, the transportation industry was doing quite well.

As part of his "market research," Luke asks the kids to help him come up with a superhero film based on their lives in kindergarten – with some hilarious results.

Despite his parents' disapproval, Nico has decided to stay in Germany. Yara is helping him take care of all the details – and has a nice surprise for him, too.

Yara and Nico argue a bit about his plans, but in the end she agrees to help him get settled in Germany.

Nico explains that he wants to change some things in his life. In particular, he is not happy being a law student.

Over a meal at Tarek's restaurant, Nico and Yara talk about home and homesickness. Then Yara explains why she went to Switzerland.

The Lochmühle Amusement Park, situated on a former pony farm near Frankfurt, offers plenty of rides and entertainment for young children.

Yara is surprised to see her nephew Nico at her shop, since she didn't realize he was in Germany. Nico, Tarek, and Yara decide to go have a meal at Tarek's restaurant and tell each other what happened.

Nico's friends surprise him with paella, one of his favorite Spanish dishes. They talk about homesickness, but Nico seems quite happy in Germany.

Lisa arrives at the hospital to see how Nico is doing – but it's not so easy to find him.

Nico's friends take him to the doctor's office, where he has an appointment to get his foot examined.

On the soccer field, Nico suddenly experiences pain in his foot. The others sit him down and take a look at it.

The guys discuss healthy eating on the soccer field. As it turns out, they have slightly different opinions about what qualifies as healthy food.

The guys might not be the good players that they claimed to be, or perhaps they are just out of practice? They debate what the key is to staying in shape.

Nico asks Tarek how often he and his friends get to play soccer together. It seems that they are all quite busy, but still manage to stay in pretty good shape.

The guys get ready to play soccer, taking inventory of their equipment and food. Nico doesn't have soccer shoes, but is able to borrow some.

Unable to figure out whom Yara would've gone to visit in Switzerland, the group decides the best thing to do is to wait for her return.

We see how Yara got a phone call two weeks ago that led to her unexpectedly flying to Switzerland.

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?
