The pharmaceuticals industry is the largest in the world. When director Ryan Penington began researching the world of "Big Pharma" for a documentary on healthcare, he had no interest in it. But when he delved deeper and realized that he had spent his entire life in a city where pharmaceutical giant Eli Lilly had been hovering over him, his film changed gears completely.

Buying the Pharm, from the producers of the 2006 indie hit "9/11: Press for Truth," uncovers the machine behind the slick ads, ever-present commercials and doctors' endorsements, showing you not only how pharmaceutical companies sell pills that don't work, but how they sell diseases to which only they have the cure.

Featuring exclusive interviews with pharma whistleblowers and medical experts, Buying the Pharm explores how prescription drugs are pitched to doctors who in turn take that pitch at face value. How do we know this is true? Because when we sent actor Jason Klamm undercover as a pharma rep to pitch cure-all drug Cashenin XR, that's exactly what happened.
