The Loiblpass is situated in the mountains between Austria and Yugoslavia: 12km from the village of Neumarktl and 10km from Ferlach in Carinthia. Between 1943 and 1945, political prisoners from the Mauthausen concentration camp drove a tunnel into the mountains at an altitude of 1200m. To this day, two people have been linked by this tunnel: Janko Tisler was an engineer in charge of the building site in 1944; today he lives in Krize, south of the tunnel. Dr. Sigbert Ramsauer, the SS doctor of the camp at the site then, at the age of 80 still practises in Klagenfurt. Janko Tisler fights against forgetting, Dr. Ramsauer wishes he were forgotten. The history of the tunnel has become theirs as well.

13 August 1961: the GDR closes the sector borders in Berlin. The city is divided overnight. Escape to the West becomes more dangerous every day. But on September 14, 1962, exactly one year, one month and one day after the Wall was built, a group of 29 people from the GDR managed to escape spectacularly through a 135-meter tunnel to the West. For more than 4 months, students from West Berlin, including 2 Italians, dug this tunnel. When the tunnel builders ran out of money after only a few meters of digging, they came up with the idea of marketing the escape tunnel. They sell the film rights to the story exclusively to NBC, an American television station.
