On the evening of June 13, 1997, smoke from an electrical fault spread through the Uphaar Cinema in Green Park, New Delhi, as a packed audience watched the film Border. Locked and obstructed exits turned hallways into traps; 59 people died—mostly from smoke inhalation—and scores were injured. The disaster triggered years of litigation, tightened scrutiny of fire-safety enforcement, and a long struggle by victims' families for accountability.
