On June 24, 1973, an arsonist set fire to the Up Stairs Lounge, a gay bar located on the edge of the French Quarter in New Orleans, Louisiana. The fire ultimately killed 32 people and severely injured countless others. For over 40 years, it was considered the "Largest Gay Mass Murder in U.S. History". With exclusive interviews from survivors, family/friends of victims and witnesses, along with long lost artifacts, newsreel footage and photos, UPSTAIRS INFERNO vividly examines this oft-forgotten story and gets inside the hearts and minds of a handful of vibrant people who experienced one of the most important and underreported moments in LGBT History.
