“I watched it on Amazon in 2019 or 2020. There is a billboard in a small town in Wisconsin, promoting this weird cult. The cult was started in the 1950s, and was cut from the same cloth as scientology, ie L Ron Hubbard-style pseudoscience etc. The billboard is the last remanent of the cult. The documentary is about the last guy who still follows it. He’s old and followed it his whole life. There’s a lady who is interviewed too, and she quit it way back in the day and feels bad for the last guy, bc he’s wasted his life on it. I can’t remember the name of the cult, but it was derived from a common male name- like something similar to “Edwardians.” I didn’t finish the documentary. From what I remember, there was no crazy Jonestown-like incident or really anything too sensational about it- was more innocuous as these things go. I have not been able to find via internet searches. The results that have come up about cults in Wisconsin (mostly Shawano) are not it.”
The cult is not the Branch Davidians.
