One year ago, Nikolas Cruz legally purchased a semiautomatic rifle, walked into his old high school in Parkland, Florida, and killed 17 people. After the event, students decided to take on the allpowerful American gun rights lobby: the National Rifle Association. Tracing the story of a student uprising unlike any seen before, this moving documentary explores how, with its five million members and many political connections, the NRA manages to keep such a permissive gun law alive, and why it has such a strong hold over American society.
