A handyman is tasked with refurbishing an old apartment in the city of Berlin, Germany. In the course of his extensive renovation work, he digs deeper and deeper into the history of the apartment. Relics from past times turn out to be silent witnesses – and former companions – of the apartment's previous inhabitants. With each new find, he tells his daughter the story behind this trace of a past adventure—with its own protagonists, in its own genre, with a very different atmosphere, but always set in the same four walls.
