Acting as their manager, he takes the two neo-athletes to Germany so they can take part in their first European competition. However, the pressure on them is enormous. To the two athletes have already racked up debts in order to get to Europe in the first place and their families have given them orders not to return empty handed. Things are not much better for Wagner: the ever-increasing competitiveness of the marathon world and a demanding wife keep him occupied.
A dramatic thriller based on the incredible true David vs. Goliath story of American immigrant Dr. Bennet Omalu, the brilliant forensic neuropathologist who made the first discovery of CTE, a football-related brain trauma, in a pro player and fought for the truth to be known.
