In 1999, 19-year-old Emmanuel Sanford-Durant and his family began filming their daily life in the most dangerous neighborhood in the United States, just 17 blocks from Capitol Hill. They haven't stopped filming since. Produced in a unique collaboration with director and journalist Davy Rothbart over a period of two decades, "17 Blocks" sheds light on a nation's current crisis through a deeply personal, raw and moving family saga.
