The Tea Party movement has taken American politics by storm. But is this truly a populist uprising or one of the greatest feats of propaganda ever seen?

Seeking to find out, Australian filmmaker Taki Oldham embeds himself in the Tea Party uprising. From men sporting tri-corner hats in Louisville Kentucky (the movement takes name from a key event in the American revolution) to 100,000 placard waving patriots in Washington D.C. ‘taking our country back’ from Obama’s ‘communist’ regime. But who are generals of this army?

Enter brothers Charles and David Koch. Oilmen, billionaires 20 times over and on a mission to create a privatized America. For three decades they’ve underwritten a propaganda war, funding fake grassroots groups (branded ‘astroturf’ by opponents) to dupe citizens into protesting on behalf of some of Americas most powerful people and corporations. As Taki infiltrates one such group, Americans For Prosperity, he captures David Koch beaming as operatives report running Tea Party events all over the country.
