Documentary look at health care in the United States as provided by profit-oriented health maintenance organizations (HMOs) compared to free, universal care in Canada, the U.K., and France. Moore contrasts U.S. media reports on Canadian care with the experiences of Canadians in hospitals and clinics there. He interviews patients and doctors in the U.K. about cost, quality, and salaries. He examines why Nixon promoted HMOs in 1971, and why the Clintons' reform effort failed in the 1990s. He talks to U.S. ex-pats in Paris about French services, and he takes three 9/11 clean-up volunteers, who developed respiratory problems, to Cuba for care. He asks of Americans, "Who are we?" 

In this documentary, the director/writer Michael Moore exposes the dysfunctional North American health care system, oriented to huge profits and not for their mission of saving lives. Further, he shows the corruption in the political system, with members of government and congress "bought" by the corporations and the situation of the average American citizens, including those that volunteered to work in the rescue mission of the September 11th. Then he travels to Canada, Great Britain and France to compare their systems showing their hospital, doctors, staffs and patients. Last but not the least, he shows that the prisoners in Guantanamo have better medical treatment than the common people in USA, and he ends getting free treatment to the Americans that participate along the documentary in Cuba.
