For 16 years, Victor Conte claimed BALCO Laboratories, his supplement and nutrition company based in the Bay Area, never dabbled in illegal performance-enhancing drugs. But by 2000, he went to the dark side and became the go-to guy for athletes in search of steroids, fame and world records. The film features interviews with several of Conte’s notable former associates — including Montgomery and the anti-doping and IRS authorities who helped send him to prison after a 42-count indictment — who give harrowing testimony as the legend of one of sports’ most notorious names continues to unfold.
