The film, made by British television producer Martin Durkin, presents scientists, economists, politicians, writers, and others who dispute the scientific consensus regarding anthropogenic global warming.

The film's basic premise is that the current scientific opinion on the anthropogenic causes of global warming has numerous scientific flaws, and that vested monetary interests in the scientific establishment and the media discourage the public and the scientific community from acknowledging or even debating this. The film asserts that the publicized scientific consensus is the product of a "global warming activist industry" driven by a desire for research funding. Other culprits, according to the film, are Western environmentalists promoting expensive solar and wind power over cheap fossil fuels in Africa, resulting in African countries being held back from industrializing.

The film won best documentary at the 2007 Io Isabella International Film Week.

A number of academics, environmentalists, think-tank consultants, and writers are interviewed in the film in support of its various assertions. They include the Canadian environmentalist Patrick Moore, former member of Greenpeace but for the past 21 years a critic of the organization; Richard Lindzen, professor of meteorology at the Massachusetts Institute of Technology; Patrick Michaels, Research Professor of Environmental Sciences at the University of Virginia; Nigel Calder, editor of New Scientist from 1962 to 1966; John Christy, professor and director of the Earth System Science Center at University of Alabama; Paul Reiter of the Pasteur Institute; former British Chancellor of the Exchequer Nigel Lawson; and Piers Corbyn, a British weather forecaster.
