On Oct. 24, 2011, 12-year-old Garrett Phillips was murdered in his home in Potsdam, a small town in upstate New York. Police quickly zeroed in on a suspect in this unthinkable crime: Oral “Nick” Hillary, a black man in the mostly white community, who was a soccer coach at Clarkson University and the ex-boyfriend of Garrett’s mother, Tandy Cyrus. The two-part documentary raises troubling questions of racial bias and issues surrounding policing and the criminal justice system.
