Dr. Grunert, electronics specialist from the GDR, gets a visit from an old acquaintance from war times. Both worked back then on navy torpedoes. His former colleague wants to poach Grunert – to Schenectady, the headquarters of the largest American electronics company. With alleged war crimes, he tries to blackmail Grunert, but quickly it becomes clear where the true criminals are sitting: In influential positions of the American industry. Grunert underestimates the scrupulousness of his opponent and invites him to a remotely located country home to clarify things. The Ministry for State Security is already on the trail of the matter and saves the engineer from a dangerous solo action.
