After their partner swap experiment takes a turn, four friends arrive at a remote beach hut to face the fallout and purge themselves of deeper truths.

Sonia breaks the perhaps most exciting time of her life, because the 20-year-old moves to Berlin for a mathematics study. Once there, she soon began to build up a new circle of friends, and then she fell in love with the kind, but irresponsible Ladja. There is only one big catch: the dear money is a bit scarce and therefore Sonia one day, financially, but also from curiosity, the path to prostitution. From now on, it leads a brisk double flight, which can fly at any time. Her experiences are ambivalent, as part-time she often gets into difficult situations, but also gets to know nice people, while she enjoys life just as a student. But how long can it maintain the double game?

A drama with a supernatural edge, this genre-crossing gem finds two couples visiting a home from their past, and sexual tension that brings out the worst in each other. Long-buried grudges resurface and it seems unlikely the couples will return intact. Faced with an outcome that will upset their delicate balance of happiness, the world offers them a bizarre opportunity to correct it.
