A micro-adventure turns into horror: The friends Ayla Ömer, Viola Klemm and Marlene Seifert try to find their way back home from the deep forest without any technical aids. They want to test whether this "dropping" in unfamiliar terrain is safe for their sheltered teenage children. But when night falls, the three neighbors from middle-class Bremen-Schwachhausen are lost in the forest - and the next morning one of them is dead.

The Bremen investigators Liv Moormann and Linda Selb encounter many inconsistencies and numerous suspects. On the one hand, there is the “cell phone man”, who years ago secretly photographed campers while they were sleeping and is suspected of murdering a woman. On the other hand, the seemingly intact facade of the well-off neighborhood with the husbands Klaus Seifert, Emre Ömer and Mirko Klemm gradually begins to crack. There are also arguments among the teenage children. Selb's aunt, Johanna Selb, has a lot of insider information about the suspects.
