In June 1990, Joel Sappell and Bob Welkos completed a five-year investigation into the Church of Scientology that culminated in a groundbreaking six-part series in the Los Angeles Times. The story Sappell didn't tell at the time was about the mystifying and unnerving events that marked his and Welkos' lives during that period. Today, as defectors from the church have gone public in tell-all books and on YouTube, Sappell sets out to investigate those unsettling occurrences, from a false arrest report to a strange CHP stop to illegally obtained personal credit reports and phone records to the sudden and ultimately fatal illness that struck his dog.
