It came out somewhere between 5 to 10 years ago (I think) I think the movie was set in LA or San Fancisco. The protagonist and one or two friends were researching a fringe science spiritualist cult reminiscent of The Dharma Initiative from LOST, or the Arboria Institute from The Black Rainbow. Early in the movie there is a scene where the protagonist is in an office building, taken to a small room, and made to watch the cult's bizarre introduction video. The protagonist and his friends go on some kind of scavenger hunt, following leads/instructions from the video he saw in order to find out more about the group.
Near the end of the film, he winds up in one of the groups gatherings which takes place in a very large, dimly lit rented hall at a hotel with a low ceiling. Lots of people standing around talking, the leader of the cult sitting on the floor with some people gathered around him.
It was VERY low buget, and I had trouble finding a copy even when it first came out. Any help tracking it down would be appreciated, I've been having dreams about this movie every night, but can't even remember most of the plot details.
