Philipp still doesn't have any peace and quiet. After fighting off the bothersome bugs, he has to deal with the loud neighbors. When he receives an unexpected phone call from Berlin, he makes a hasty departure. 

Philipp heads for Berlin. Due to the unfriendly weather, getting there is easier said than done. Along the way, Philipp makes a few acquaintances. 

The editorial staff at Radio D is waiting for Philipp. Paula and Ayhan, his future co-workers, are killing time. But there's no sign of Philipp and the telephone lines are down. 

Paula and Ayhan welcome their new co-worker to Radio D. They already have a pressing assignment: The late King Ludwig of Bavaria is supposedly still alive and the teams wants to investigate. 

In Neuschwanstein Castle, Paula and Philipp meet a secretive stranger who is wearing King Ludwig's cloak. They do some research on the mysterious circumstances surrounding Ludwig's death. 

At Neuschwanstein Castle, Paula and Philipp question the would-be King Ludwig. Paula stumbles on an interesting discovery and finds a clue as to who the mysterious stranger really is. 

Philipp also finds a clue to the stranger's identity. He sees an ad in the newspaper for a musical about King Ludwig. On the way there, he interviews tourists visiting from all over the world. 

Philipp meets the actor playing the role of King Ludwig in the musical and asks him to do an interview. Suddenly he recognizes the man's voice. Meanwhile, an unexpected visitor turns up at the Radio D office. 

Where does the name Eulalia come from? Compu, Ayhan and Josefine look into the meaning and come up with several different answers. A Spanish co-worker helps them out. 

If there's something you don't understand, it's always good to ask. The professor answers the questions about past episodes that Radio D listeners have sent in. 

Not everyone at Radio D is excited about Carnival. Compu's assignment takes the two journalists to the Black Forest, where the Carnival spirit is strong. 

From the streets, Paula and Philipp report on Carnival once again. They discover different kinds of costumes and even learn a few German dialects along the way. 

Both journalists are fascinated with Icarus, the tragic hero from Greek mythology. But do the listeners know who Icarus was? Paula and Philipp tell his story. 

When mysterious circles are discovered in a corn field, Paula and Philipp go to investigate. Did a UFO land here, or is somebody trying to pull a prank? 

Paula and Philipp want to get to the bottom of the crop circles and go at night to investigate. But what they find doesn't appear to be the work of aliens. 

Although the crop circles were made by the farmers, Eulalia still believes that UFOs exist. Philipp and Paula's investigation into the fraud takes them to the local pub, where they talk with the villagers. 

When the temperature in the Radio D office becomes unbearable, Paula and Philipp are glad to get an assignment that takes them to the coast, where a shark has been spotted in the port basin. 

Philipp and Paula search for traces of the shark and make a peculiar discovery. A surfboard without a surfer in the port basin and a confusing newspaper article peak their interest. 

Paula and Philipp solve the mystery of the shark sighting and once again uncover a fraud. However, the reason for the staged incident is unclear at first. 

Eulalia the owl helps get Paula and Philipp on the right track. They discover that their co-workers from the Hamburg newspaper are in on the game. 

The journalists try to understand the term "getürkt" and visit an unusual port where every ship is greeted in a particular way. 

It's a sad day in the Radio D office. Ayhan is saying goodbye and moving back to Turkey. Although his co-workers have prepared a surprise for him, the farewell party can't lift the blue mood.
