The film begins with an emotional montage of football player Mike Webster's life, portrayed by David Morse, showcasing his glory days with the Pittsburgh Steelers, juxtaposed with a heartfelt conference where his struggles are evident. Fast forward to September 2002, and the viewer is hit with a shocking contrast: Mike now finds himself homeless, living inside his car, grappling with the devastating effects of dementia.
Amidst this somber reality, Dr. Bennet Omalu, depicted by Will Smith, is seen providing crucial testimony in a murder trial. His astute observations reveal that blood found on the accused does not belong to the victim, a critical point given that the defendant suffers from hemophilia, rendering him incapable of the risks associated with such violence.
Bennet is employed at the coroner's office in Allegheny County, where he harbors a unique routine of conversing with the deceased, using their silent stories to unravel the cause of their demises. His relationship with his colleagues is a mix of camaraderie and rivalry; he gets along well with Gracie (Sara Lindsey), yet grapples with tension from Danny (Mike O'Malley). An incident arises when he discards surgical knives after just one use, prompting a provocative discussion with his boss, Dr. Cyril Wecht, played by Albert Brooks. Bennet's dark humor shines through when he queries Cyril if he'd be okay with him using the same knife on his mother as he did on a serial killer. Cyril’s response is surprising, revealing his own twisted perspective.
As Bennet navigates his professional life, he crosses paths with a young immigrant, Prema Mutiso, portrayed by Gugu Mbatha-Raw. The two develop a strong connection, with Bennet offering help in a way that initially offends Prema. His intentions are clear as he emphasizes the importance of accepting assistance, suggesting that it’s not a sign of weakness but rather a necessary step on the path to success in America.
Meanwhile, the tragic unraveling of Mike Webster continues. His visit to Dr. Julian Bailes, played by Alec Baldwin, illustrates the severity of his deteriorating health. Webster meets up with fellow player Justin Strzelczyk, played by Matthew Willig, who is also grappling with mental health issues. A chilling moment surfaces when Mike admits, "I don’t want to go to sleep," leading him to engage in risky behavior to remain awake. Tragically, Mike's life comes to a devastating end.
Following Mike’s shocking death, the storyline takes a poignant turn. Bennet examines his brain and discovers critical evidence of severe head trauma, signaling a link to Chronic Traumatic Encephalopathy (CTE). As he digs deeper into his research, studying footage from football games, he becomes increasingly aware of the violent impacts players endure.
As Bennet's relationship with Prema blossoms into love and marriage, reality hits hard as more players succumb to tragic circumstances, mirroring Webster's fate. Strzelczyk, amid mental tumult, is found dead, and the tragic narrative continues with Terry Long, who dies from a toxic substance. This grim string of events leads Bennet to present his findings; however, he is confronted with fierce resistance. His connection to the NFL, and the dangers of football, casts a shadow over his work, earning him both allies and enemies.
In a gripping dinner scene, tensions rise between Bennet and Dr. Joseph Maroon, who dismisses Bennet's warnings as destructive to the sport they both admire. As Roger Goodell takes over as NFL commissioner, Bennet’s revelations start to make waves, leading to an internal conflict when his message about player safety is obscured by corporate politics. This conflict escalates when corrupt FBI agents target Bennet and Cyril, attempting to derail his efforts and silence the truth about the NFL's negligence toward player health.
An unsettling incident occurs when Prema, alone while driving, senses that someone is following her, leading to a harrowing detour that lands her in the hospital, where they learn devastating news about their unborn child. Bennet, already burdened by the pressures and losses, finds himself spiraling into despair as he faces the harsh reality of selling his home.
Years later, despite the challenges they've faced, Bennet and Prema resettle in California with their daughter, but the specter of former football players continues to loom large. The tragic news of Dave Duerson's suicide stirs Bennet back into action, as he is called upon to examine Duerson's brain for the insights it may provide.
In a powerful culmination, Bennet speaks passionately about his research while balancing his admiration for football against the stark truths he has uncovered. The parallels drawn between tobacco companies' denial of health risks and the NFL's stance on concussions reverberate across the nation. As Bennet receives recognition for his work, he is offered a prestigious position in Washington, D.C., symbolizing his resilience and commitment to safeguarding future players.
Ultimately, Bennet chooses family over career, remaining in California with Prema and their two children. The story closes with an impactful statistic: 28% of football players may face CTE, while the NFL faces a slew of lawsuits stemming from its unwillingness to transparently address the health ramifications of concussions. Remarkably, all charges against Dr. Cyril Wecht are dropped, and Bennet Omalu officially becomes a U.S. citizen in February 2015, symbolizing victory amid adversity. In the finale, as he drives past a football practice, Bennet watches young players collide, a poignant reminder of the ongoing battle between safety and the sport they love.
