Marc Headley provides a rare, never before seen insider's look at life inside Scientology. He spent 15 years at their secret headquarters - a 500 acre property located deep in the California desert. The local townspeople were told lectures and films were made there. But is that all that was happening? It is the location of a multi-million dollar home for L. Ron Hubbard, built two decades after his death. It is the home of Scientology's current leader, David Miscavige. So what really happens there? Are the stories on the internet true? How does Scientology conduct management of its day to day operations? Could stories of armed guards, weapons, staff beatings, and razor wire fences be true? If so, how could a facility like this exist in modern day America? Hundreds of staff tried to escape over the years. Some succeeded but were never seen or heard of again, most failed. Why were people kept here? What was it that went on at the headquarters of Scientology? This is the story of what happened behind the Iron Curtain of Scientology.
