Where can I watch The Best of Enemies in United States?

Centers on the unlikely relationship between Ann Atwater, an outspoken civil rights activist, and C.P. Ellis, a local Ku Klux Klan leader who reluctantly co-chaired a community summit, battling over the desegregation of schools in Durham, North Carolina during the racially-charged summer of 1971. The incredible events that unfolded would change Durham and the lives of Atwater and Ellis forever.
