East Germany, 1975. Karin Müller, sidelined from the murder squad in Berlin, jumps at the chance to be sent south to Halle-Neustadt, where a pair of infant twins have gone missing. But Müller soon finds her problems have followed her. Halle-Neustadt is a new town—the pride of the communist state—and she and her team are forbidden by the Stasi from publicizing the disappearances, lest they tarnish the town's flawless image. Meanwhile, in the eerily nameless streets and tower blocks, a child snatcher lurks, and the clock is ticking to rescue the twins alive.
