After graduating from Harvard, Bryan Stevenson heads to Alabama to defend those wrongly condemned or those not afforded proper representation. One of his first cases is that of Walter McMillian, who is sentenced to die in 1987 for the murder of an 18-year-old girl, despite evidence proving his innocence. In the years that follow, Stevenson encounters racism and legal and political maneuverings as he tirelessly fights for McMillian's life.
