UNDER THE GUN examines the events and people who have kept the US gun debate fierce and the progress slow, even as gun deaths and mass shootings continue to increase. Through the lens of families impacted by the mass shootings in Sandy Hook, Newtown, Aurora, Isla Vista and Tucson, as well as those who experience daily gun violence in Chicago, the documentary looks at why politicians are finding it difficult to act and what is being done at the state and local levels. The film is executive produced and narrated by US Journalist and News Anchor Katie Couric.
