It also stars Alec Baldwin, Gugu Mbatha-Raw, and Albert Brooks. In 2002, former Pittsburgh Steelers center Mike Webster is found dead in his pickup truck, after years of self-mutilation and homelessness. Before his death, a fellow football player, Justin Strzelczyk, comes to him, and confides that he is starting to lose his memory, that he is saying odd things to his children, and nearly threw his wife against the wall. A disoriented Webster brushes the worries off, and deliriously tells him that the most important thing "is to finish the game," which is what he said during his Hall of Fame speech. Bennet Omalu, a forensic pathologist with the Allegheny County, Pennsylvania coroner's office, handles Webster's autopsy. He wonders how a man, otherwise healthy, and fairly young, could have degenerated so quickly, and makes it a point to figure out why he died of a heart attack at only fifty. Omalu closely examines microscope slides of Webster's brain and discovers that he had severe brain damage. He ultimately determines that Webster died as a result of the long-term effects of repeated blows to the head, a disorder he later calls chronic traumatic encephalopathy (CTE). With the help of former Steelers team doctor Julian Bailes, fellow neurologist Steven T. DeKosky and county coroner Cyril Wecht, Omalu publishes a paper on his findings, which is initially dismissed by the NFL.
