A love connection clicks for Lila when she moves back to Berlin and meets Christopher -- never realizing that she's fallen for a rock star who's signed a contract to remain single for life.

August 1961: To earn a bit of West German money, East Berlin "plaselayer" Hans Kuhlke smuggles scrap metal to his friend Erwin Sawatzke in West Berlin. One evening, he and his wife are invited to the Sawatzkes' house. Meanwhile, their son Paul stays with a friend in East Berlin. On this summer night, the political situation in Berlin comes to a dramatic head: the borders are closed and the construction of the Wall is initiated. The disappearance of his parents leaves 14-year-old pioneer Paul torn between family ties and loyalty to the party. At the last second, he sees through his role in the system and is taken in by his piano teacher. Together they plan their escape to the West - but it turns into a race against time.
