A story about searching and finding, leaving and returning, remembering and rediscovering. War ruins, demolition excavators, and cranes dominated the cityscape when eight-year-old Andreas left Berlin with his mother because she had been accepted into a study program in Moscow. What was planned to be a year turned into a lifetime. Andreas became Andrej and a Germanist. After 45 years, he returns to his birthplace and explores the places of his childhood. Below Mont Klamott, where the crane track once ran, people now live in listed buildings.

Andrej gets to know the most popular piece of furniture in the GDR. He meets an American who caused a stir in Volkspark Friedrichshain with a Frisbee. The inventor of the P2 prefab building type explains how the pass-through made its way into industrialized housing. Former Prime Minister Hans Modrow describes his life on Stalinallee and how he experienced de-Stalinization. A resident of the gallery house on the grand boulevard recalls June 1953, when she marched with the construction workers from there to the House of Ministries.

Finally, Andrej meets Mrs. Schiltzer, who, along with her husband, was tasked with a major encryption project in the 1950s. And suddenly, he finds what he has been searching for all along. The audio walk begins at the Platz der Vereinten Nationen and lasts about two hours.
