What if confronting the climate crisis is the best chance we'll ever get to build a better world? Filmed over 211 shoot days in nine countries and five continents over four years, This Changes Everything is an epic attempt to re-imagine the vast challenge of climate change. The film presents seven portraits of communities on the front lines, from Montana's Powder River Basin to the Alberta Tar Sands, from the coast of South India to Beijing and beyond. Interwoven with these stories of struggle is Naomi Klein's narration, connecting the carbon in the air with the economic system that put it there. Throughout the film, Klein builds to her most controversial and exciting idea: that we can seize the existential crisis of climate change to transform our failed economic system into something radically better.

Naomi Klein gives a lecture tracing the confluence of ideas about modifying behavior using shock therapy and other sensory deprivation and modifying national economics using the "shock treatment" of Milton Friedman and the Chicago School. She moves chronologically: Pinochet's Chile, Argentina and its junta, Yeltsin's Russia, Bush and Bremer's Iraq. A trumped-up villain provides distraction or rationalization: Marxism, the Falklands, nuclear weapons, terrorists; and, always, there is a great shift of money and power from the many to the few. News footage, a narrator, and talking heads back up Klein's analysis. She concludes on a note of hope.
