The condition of the aquatic habitat is checked at regular intervals by conservationists and some interesting discoveries have already been made. Meanwhile, the ospreys are gradually training their young to become independent.

The allure of the Feldberg Lakes with their clear, fresh water was described many years ago by the writer Hans Fallada. In the last part of this series, you can see how professional conservationists and volunteers are helping to preserve these impressive waters.

Extr@ is a language education television series not unlike the sitcom Friends. In this first segment, we meet the main characters, roommates Anna and Sascha.

Sascha and Anna are really excited because Sam is supposed to be arriving at their place today. However, when the doorbell rings, they are disappointed to see that it isn't Sam after all...

The doorbell rings again and this time it really is Sam at the door. Communication proves to be difficult from the very first moment...

Sam is at the door and is completely different from what Sascha and Anna had imagined him to be. And there are plenty of misunderstandings...

Sascha and Anna go out food shopping. Nic stays in the apartment with Sam and gives him a little German lesson...

Sascha and Anna return to the apartment from the store and find him riding Sascha's bike. That's the final straw for Sascha and she's about to kick him out. But then, of course, everything turns out differently!

Sascha and Anna allow Sam to stay with them after all. Suddenly, just as they are all about to go out and party together, the doorbell rings...

Sam turns out to be a late sleeper, and the girls are a little surprised by his pajamas!

It's clear that Sam needs some new clothes, but Nic, Sascha, and Ana have very different ideas about how he should dress.

Sascha, Anna, and Nic go clothes shopping for Sam, leaving him in the apartment. Suddenly the phone rings...

Sam tries on the clothes his new friends have bought him in the bathroom, while they wait eagerly for him in the living room.

As Sam can't be left to do the shopping alone, the three friends have to come up with a way to teach him.

Having practiced with Anna and Sascha, Sam now wants to go out shopping on his own. The other three stay home because Anna and Sascha are ill. Nic is on nursing duty. Suddenly, the tarantula calls!
