An investigative (but frequently humorous) documentary on the surveillance activities of the New York City Police Department's Bureau of Special Services, known as the Red Squad. "An extraordinary political film, in which the spies - Red Squad and undercover police assigned to infiltrate the American Left - are in turn spied upon. The result: a photographic exposé of faces and agents in action, fully identified by name and title."

- Amos Vogel, Film as a Subversive Art
