On June 28th, 2013, lightning sparks a wildfire near the town of Yarnell in central Arizona. Fueled by dry conditions, the fire quickly spreads. To contain the blaze, local officials call in elite crews of firefighters known as hotshots. One team, the Granite Mountain Hotshots, from the nearby town of Prescott, are especially eager to prove themselves. But they’ve never faced anything like the Yarnell Hill blaze.
