In this documentary which aired last week during Holy Week on British television, skeptic Derren Brown reckons faith healers are just wicked con artists and in his latest stunt, he sets out to show how they're using the same tricks as any stage hypnotist.
To prove the point, he's spent six months training a scuba diving instructor called Nathan to "heal" the sick.
And at the climax of this programme we'll see Nathan get on stage in Dallas, Texas, to attempt to convince an audience that he's the real deal.
