Scientology is a "religion" founded by Ron Hubbard, a science fiction writer who had previously talked about starting a for profit religion. The religion takes in oodles of money from its members so they can do arbitrary theton level tests.
A camera man tries to go into a scientology fair. He isn't permitted to go into the fair because it's a private party, even though it's held on a public street with permits. The camera man gets even better footage than what he could have gotten at the fair, the cults' psychology towards people who are against the church.
Apparently the three men are convinced from so much brain washing that anyone who is against the church doesnt want people to get better, and are hiding their own, sick and vile, crimes. They feel it for a fact, and continue to probe the camera man to admit his crimes, so they can begin to "help" him.

Search Google Video for Scientology, tons of results. John Travolta was supposedly not going to treat his poor kids autism because scientologists believe psychiatry and medicine is evil.
