As former National People's Army border guard the Berlin Schaller returns once a year to his old operation site. Wild nature overgrows the once clear-felled area of the border region. The landscape is changing rapidly. Schaller remembers how he was exposed to fear and mistrust during his term of service. He sees himself patrolling with Corporal Mazze for the first time. His trust is consequentially put to test and he has to experience what friendship can mean in such a situation.
