The Bentley Effect recounts the story of citizens throughout the Northern Rivers shire of Australia protesting against coal-seam gas extraction. When the community first learns of the news, a critical mass of people from all walks of life--farmers, landowners, mums, dads, activists, and scientists--come together to rally against the invasion. But despite enormous public opposition, the gas industry and the State Government are determined to see their plan through. So the community changes tact and resorts to differing methods of civil disobedience and non-violent protest. This culminates in a music festival of sorts in Bentley, New South Wales, which brings together the community and also spurs them on to initiating political action.
