Concussion, starring Will Smith, is based on the true story of American immigrant Dr. Bennet Omalu, a forensic neuropathologist, who is known for looking deeply into the autopsies he performs to learn more about why people died. Dr. Omalu wades through this dramatic thriller by making waves in the scientific community by discovering a brain injury that has the power to topple the NFL.

Running side-by-side with Omalu’s story is the story of several different NFL players experiencing trouble after their careers have ended. They display erratic behavior, aren’t themselves, and the people that they turn to for help seemingly have no idea what to do. When a pro football player shows up dead and Omalu has to do the autopsy, he discovers trauma that will change the NFL forever.

Dr. Omalu made the first discovery of CTE, chronic traumatic encephalopathy, a progressive degenerative disease found in people who have a history of repetitive brain damage. After paying for tests out of his own pocket for various football players, Omalu discovers that this traumatic brain injury is something that more football players will suffer from and that they should all be made aware of CTE. After publishing a paper with his findings, Omalu begins fighting for the concussion truth to be heard. He finds major pushback from both the NFL and the public with threatening phone calls to his house, visits from the FBI, and other doctors dismissing his findings among just some of the threats. The National Football League works to quiet Omalu’s findings, something that he simply cannot allow. This movie follows Omalu’s journey to make the NFL acknowledge CTE and the incredible uphill battle he faces to make the public believe his findings.

This movie is based on a book Concussion by Jeanne Marie Laskas.
