On October 1st, 2017, over 22,000 people gathered in Las Vegas for the annual Route 91 Harvest music festival, which featured some of country music's biggest stars. As closing act Jason Aldean performed his set, a gunman opened fire on the throng of concertgoers from the 32nd floor of the Mandalay Bay casino and unleashed over 1,100 rounds of ammunition in just 10 minutes. Fifty-eight people were murdered, and over five hundred others were shot, making it the worst mass-shooting in U.S. history. Using interviews, eyewitness testimony, and haunting cell-phone footage, acclaimed director Charlie Minn recreates the scene from that harrowing night and pieces together the variables surrounding the incident. Focusing on the survivors and their stories, Minn creates a narrative of the shooting and its aftermath that provides some solace and reveals a community that chose to be #VegasStrong in the face of terror.
