Miracles, expensive cars, exorcisms and bodyguards: religion is big business in Nigeria. Reporter Seyi Rhodes and director Matt Haan travel to Lagos to reveal the extraordinary world of the millionaire preachers. By promoting the dream of escaping poverty, they have turned their churches into corporations, which are changing the face of Christianity. Every Sunday millions of Nigerians crowd into thousands of competing churches. The team visits one church in Lagos run by Dr Sign Fireman, an up-and-coming preacher who is attempting to break into the big time. They find 2000 people at an event billed as the Burial of Satan. After a rock star entrance, Dr Fireman begins his service by exorcising the demons in his congregation.
