We travel to the Enhanced Games training camp in Las Vegas to meet the competitors at the heart of this experiment. Former world champion Ben Proud, who walked away from the Paris Olympics with a silver medal and a looming question: who was he without swimming? And Megan Romano, a retired world champion who spent nine years away from the pool before getting the call. They're chasing speed, financial security, and a shot at something they never quite got when they were playing by the rules. The only catch: they'll be the first athletes in history to do it openly, on performance-enhancing drugs, in front of the world.
