Private detective Ferdinand Zankl is arrested by the Passau police on suspicion of murder. He is suspected of having killed his ex-girlfriend, an animal shelter manager.

In this four part episodic film, young people from Rostock live through a day of setbacks, secrets and revelations.

Suse and Ulla are happy together. They live in the country with Ulla's son Karl and enjoy the summer. One day Tom comes by. Tom is Suse's ex - and he is on his way to a rehab clinic. But over the course of the morning it becomes clear: Tom is not yet really comfortable with the fact that Suse has split up with him. And Suse's hope that Tom has grown up a little bit through the planned rehab is soon dashed.
