Der Mauerschütze.

The GDR casts its shadow right up to the present day: Stefan Kortman, a respected doctor in Hanover, carries a dark secret with him. Nobody in his home country knows that he was a Wall sniper and shot the husband of a young, pregnant woman trying to escape at the German-German border. Despite all his successes in his professional and private life, Stefan still can't find peace 20 years later. He wants to explain himself to the fugitive from back then.
