13th is a 2016 American documentary by director Ava DuVernay. The film is titled after the Thirteenth Amendment to the United States Constitution which theoretically outlawed slavery. The full amendment reads as follows: "Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction." DuVernay's documentary deals with the way racial inequality in the justice system means that slavery is still being perpetuated. Filmed in secrecy the movie was only revealed after it was announced as the opening film for the 2016 New York Film Festival. It is set for an October 7, 2016 release date via Netflix.
