The filmmakers began following the investigation into Bland's death ten days after she was found hanging in a jail cell in Texas three days after she was arrested during a questionable traffic stop.
One of Bland's sisters spoke to ABC7 about the documentary, which she said answers some questions.
Bland's death was ruled suicide, but her family has a hard time accepting that.
