In 1989 Berlin, Sascha is a young East German border guard and Franzi is a lively young West German woman who's just moved into a flat next to Sascha's watchtower at the Berlin Wall. It takes only a slight mishap and a selfless act of chivalry and the two fall in love. But soon the Stasi believes they are witnessing the start of a revolt. Afer all, this is the time of mass protests and East Germans taking refuge in the West German embassy in Prague. Franzi and Sascha must find ways to stand up for their love and strive for the impossible: to bring down the wall.
