In February 1986 they received the call of a fatherland that no longer exists: four young GDR citizens on the verge of adulthood see themselves forced, like so many others in East and West Germany, to do their one and a half years of military service. What is special: Their service area is the border system, an anti-imperialist protective wall according to their superiors, death strips and prison bars for a population incapacitated in naked reality. Now, seventeen years later, there is a reunion with the comrades and the old post. This feature film, which was the first in reunified Germany to deal with the inner workings of the GDR border troops, tells of life on the fence, the associated contradictions and some hot phases in the Cold War.
