After the fall of the Berlin Wall, a former East German spy resolves to find out who betrayed her and why — and use her lethal skills to exact revenge.

1949. Grafenberg in Brandenburg shortly before the foundation of the GDR. Here lives Michel Hollmann and works in roadmaking. His purpose in life are his wife Lotte and the two children Gerda and Heinz, for whom he is reconstructing a summerhouse into a “nest”. In Grafenberg, his siblings are living as well: His brother Karl, the mayor, and sister-in-law Edith, who works in a textile factory, with their son Jürgen. Edeltraut, his sister, has married the lamp fabricant Berthold Bennert and leads a well-off life. They as well have a son: Harald. Part of the family are further sister Hanna and brother-in-law Hermann, who is a fisherman on one of the local lakes and conducts a tenacious private war against old Stegewald and his presumptive prince-electoral rights. They are living their lives with their large and small conflicts, with different intentions, and yet remain connected always.
