Lerchenberg is a satirical sitcom produced for ZDF's 50th birthday. The plot centers on Billie, a young ZDF editor who wants to develop innovative productions for the station. When her supervisor tells her that washed-up actor Sascha Hehn, of all people, is going to get a lead role, Billie is stunned.

After Billie returns from her pitch meeting with Dr. Wolter, everyone is excited to meet the hero of the innovative new ZDF series. But nobody expected has-been actor Sascha Hehn to take the lead role…

Sascha Hehn does not want to take the supporting role he’s been assigned — instead, he opts to audition for the lead role, adding a few inappropriate touches of his own. The casting team is horrified! Can Billie fix the situation?

Doctor Wolter hands over Billie’s film project to Billie’s trainee, Judith, and tasks Billie with arranging Sascha Hehn’s comeback. Can she convince the washed-up star to take a less-conventional role?

Billie’s bad day gets even worse when Philipp tells her that he will now be dating her intern! Meanwhile, Sascha Hehn isn’t feeling so lucky either: His comeback isn’t materializing, and he now has to face the consequences of his illegal parking.

Billie visits Sascha Hehn in his hotel room and insists that he could still make a comeback – but Sascha’s not exactly in the best situation in his private life.
