The Tunnel

East German swimmer Harry Melchior (Heino Ferch) escapes to West Berlin in 1961, but is forced to leave his family behind. When he recruits pals Mathis (Sebastian Koch), Vic (Mehmet Kurtulus) and Fred (Felix Eitner) to help him dig a tunnel under the wall so he can bring his sister, Lotte (Nicolette Krebitz), to freedom, he discovers that countless others are looking for ways to get relatives out of East Berlin. Suddenly, a small tunnel becomes a major engineering undertaking.
