From humble beginnings in a suburban Sydney warehouse to an international pentecostal powerhouse, Hillsong has changed the world around it, filling stadiums with screaming congregations and counting politicians, business tycoons and A-list celebrities among its true believers.

Talking to one of those believers, who's since turned her back on Hillsong, reporter Stephen Drill found himself asking: How did the church get so powerful? And is Hillsong really everything it claims to be?

On his journey to find out the truth, Stephen follows the money, exposing disturbing claims of worker exploitation, complicated consensual sexual relationships and a culture where women are allegedly told to physically submit to their husbands.

A ground-breaking eight-part investigation, Hillsong: faith on trial will leave you asking what you can believe in.
