The Indecent Profit(1978)

Criminal police and antitrust officials arrive at the headquarters of a plastics raw materials factory. They pored over files, seized materials, and discovered price lists, which were, of course, encrypted. Their suspicions of illegal price-fixing with apparent competitors, driven purely by greed, grew stronger and were ultimately confirmed, but they were unable to prove them. Bernd Schiedel, the company's sales manager and caught in the conflict between loyalty to his employer and the company, had initiated the operation himself by providing information.
