Basically, the documentary is about how the Drug Industries (Big Pharma) are trying to shut down natural therapies, despite natural therapies being very successful in treating cancer and other ailments. The documentary shows how Big Pharma first gained control and influence over the teaching system/medical schools, then they gave the AMA the power to exclude all other doctors from practicing, then they took over the entire drug testing process, heavily influencing the medical publications and reviewing of those drugs, and finally they extended their control over the FDA which is supposed to verify the safety and efficacy of the drugs.
In the latter part of the video, it tells what happened to a few people and doctors who found a natural cancer cure and started successfully treating many people with recorded documents. These doctors were labelled quacks, harrassed, jailed, and their clinics were shut down. They weren't even given a chance, Just so Big Pharma can make Big Bucks by selling their expensive chemo drugs and carry on in their heinous crime against humanity...
