Description：Adapted from the article "GameBrain" published by Jeanne Marie Laskas in GQ in 2009. The film mainly describes the brain neurologist Bennett Omalu who first discovered that athletes are prone to chronic traumatic encephalopathy (CTE), which can cause athletes to have suicidal thoughts. The story is adapted from real events and tells the story of Bennett Omalu, an American brain neurologist who was the first to discover that American football players have a high probability of chronic brain lesions due to their occupation, and decided to make this research public. However, this research was strongly denied by the National Football League, which put Bennett in a crisis that would have a strong impact on his career.
