Content: The young East Berlin Romeo agent LARS WEBER (Tom Schilling) is smuggled into the west of the city. There he is supposed to find LAUREN FABER (Sofia Helin) in order to give the Stasi access to sensitive information from the British secret service. When the mission takes an unexpected turn, his West Berlin commanding officer RALF MÜLLER(Ben Becker) unceremoniously sets him up with NSA employee SABINE CUTTER (Friederike Becht). A momentous decision, as it soon turns out, because his connection to her goes far beyond his original assignment.

While nobody in the East knows about Lars’ mission in the West, events at home are also coming to a head. Lars’ father GREGOR(Jörg Schüttauf), a loyal socialist, increasingly doubts the political convictions for which he has been prepared to sacrifice so much. His brother CONRAD(Godehard Giese), whose marriage to GITA(Anja Kling) is nothing more than a farce, has to watch as his youngest daughter KLARA (Stephanie Amarell) is forced to dope for socialist success in the competitive sports program.

Another narrative thread develops around the homosexual teacher AXEL(Hannes Wegener), who falls in love with the British globetrotter DUNCAN(Richard Pepper) from the West and whose longing to leave East Germany grows with each passing day.
