When BBC reporter John Sweeney last investigated the Church of Scientology - supported by Hollywood stars like Tom Cruise and John Travolta - three years ago, he was spied on by sinister strangers and condemned as a bigot by the church's leaders.
Fearing brain-washing, he lost his temper and exploded, the video of which then mysteriously appeared on Youtube.
Now, as Sweeney returns to investigate the church again, this time, one of the officials has turned whistleblower to help him reveal its dark secrets, and a host of ex-Scientologists tell Sweeney shocking allegations - which the organisation denies - about this religion of the stars.
The Secrets of Scientology tells the story of what was going on behind the scenes back then - and what is happening now.
