This is the story of one man's fight against a multibillion dollar colossus. A man who stood up for what was right, whatever the cost.
The brilliant young forensic pathologist had no idea that the body on the slab in front of him would change his life, and ultimately change the world.
The body belonged to legendary American Footballer Mike Webster, whose mental health had rapidly declined after he had stopped playing - he had ended up Tasering himself to relieve his chronic back pain and fixing his rotting teeth with Superglue.
Dr Bennet Omalu found that the psychosis suffered by "Iron Mike" was no accident. His autopsy unearthed evidence of a trauma-related disease - the direct result of years of blows to the head in games. He knew it would keep killing scores of other sportsmen, including rugby players, unless something was done. He believed that the NFL (National Football League), one of the most powerful corporations in America, would welcome the discovery. But it was the one truth they wanted to ignore.
Omalu himself became a target.
'This is classic David and Goliath stuff, and as exciting as a great courtroom drama. A riveting, powerful human tale . . . a masterclass on how to tell a story'
