en Altadefinizione. Why does a religious community need a secret service? Frank Nordhausen and Markus Thöß explore this question in their documentary about the most mysterious department of the Scientology organization. They spent more than a year researching with a camera in Europe and the USA. The 90-minute documentary is the world's first detailed film about OSA - the Office of Special Affairs. Scientology is classified as an extremist sect in various European countries and is therefore monitored by domestic intelligence services.
