I am looking for an older movie that takes place in a small town. A new high school student moves to town and notices the different groups, her friend has a conspiracy that they are all being brainwashed. They end up getting to him and he changes, becomes really smart and obsessed. She ends up getting taken to the place where they brainwash the students to make them smarter. There is a janitor that has rat repellers. She ends up escaping and tries to save her friend. I don't know if they implant a microchip or anything but they make them watch some kind of movie thing while they are restrained in the chair.

Disturbing Behavior (http://www.imdb.com/title/tt0134619/)
