Hidden in the middle of Berlin, ex-spies Simon and Meret run the safe house called "The Nest." When a threat they thought was eliminated catches up with them again, they suddenly have to hide from hit men, Russian agents, the Federal Intelligence Service (BND), ex-lovers and a lot of people they have wronged—and try to keep their marriage intact at the same time.

A family must deal with the unresolved emotions and misunderstandings that deeply affect their relationships with each other. From the mother that wants to graduate from her marriage, to the daughter who discovers her husband's well-hidden secret, the family must learn to rely on and communicate with each other.
