Netflix Playwright and talented amateur cyclist Bryan Fogel’s self-administered experiments with performance-enhancing drugs are just the opening chapters of this gripping story. By pure luck, Fogel enlists the services of a Russian doctor named Grigory Rodchenkov, who 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? That was 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).
