Director Ezra Edelman examines race and celebrity through the life of OJ Simpson. Beginning at the emergence of his football career at the University of Southern California, the documentary tracks his rise in the National Football League, his television career, and his relationship with Nicole Brown - including allegations of domestic abuse and the eventual murder of Brown and her boyfriend, Ron Goldman - juxtaposing Simpson's story against the mounting racial tensions and strained relationship between law enforcement and the African-American community in Los Angeles.
