Rosa, who lives from fishing in the lakes around Berlin, wants to invest more in her relationship with Kirsten, an architect who spends all her weekends in her house on the waterfrony. The arrival of two young women, who put their tent near the house, endangers the delicate balance between Rosa and Kirsten. Supported by the play of Nele Rosetz, who is superb as a solitary fisher woman, the film alternates images of the wild German nature and longing desire, depicting two couples who discover a polyamourous, intergenerational relationship.
