This incredible sports documentary starts out in moderately promising fashion. It seems as if the film’s director, talented amateur cyclist Bryan Fogel, is content to make a sports-doping version of the fast-food doco Super Size Me. However, Fogel’s selfadministered experiments with the instant benefits and lasting after-effects of performanceenhancing drugs are just the opening chapters of a gripping story with many twists and turns. By pure luck, Fogel enlists the services of a gregarious Russian doctor named Grigory Rodchenkov as an adviser for his project. Little does Fogel know that Rodchenkov is about to become one of the most notorious figures in the history of systematic doping. Remember when Russia got kicked out of the 2016 Olympics? Many regulatory authorities will tell you that was all because of the cunning misdeeds of Rodchenkov. Amazingly, he’s only too happy to share all his tricks of the trade while the cameras are rolling (and Russian President Vladimir Putin makes his displeasure known).
