Frackman introduces us to Dayne Pratzky, who is looking to build a simple home on his block of land in central Queensland, Australia. But one day the gas company comes and demands access to his land for gas mining. Dayne doesn't want that, but is told he has no right to refuse access to his land, and so begins his transformation into a reluctant activist on a journey that takes him around the world. Through his efforts, we see other people drawn into the battle of fending off rapacious coal-seam gas miners. Frackman presents this story, crossing ideological divides, bringing together an alliance of farmers, conservationists, political conservatives, and a cast of colourful Aussie bush characters, determined in different ways to stop fracking from destroying the land.
