A mining engineer acting as a technical translator is suspected of industrial espionage after sending an innocent telegram that is intercepted by a militant snoop. Placed under investigation and reassigned to a less sensitive department, but never informed of the reason for his demotion, he petitions to get his job back, sparking an increasingly obtuse series of Party meetings.
