Fracking is going to make America one of the world's leading energy producers and has become the target of a concerted campaign by environmentalists who want it banned. In FrackNation McAleer travels across the USA and Europe to uncover the science suppressed by environmental activists and ignored by much of the media. He talks with scientists and ordinary Americans who live in fracking areas and who tell him the truth behind the exaggerations and misrepresentations of anti-fracking activists.
