Will the world ever forget that fateful June of 2013? Now, a heroic group of nineteen selfless men rush in the mouth of the raging inferno, to protect the lives and homes that stand in the way of the rampaging, all-consuming flames, only to find themselves trapped in the heart of the exitless Yarnell Hill Fire. Before long, as the men yearn to prove their mettle, a bolt of dry lightning ignites a seemingly controllable wildfire near Yarnell, Arizona but, Eric already knows that all fires are unpredictable. With determination, self-sacrifice, and the aid of Division Chief, Duane Steinbrink, Marsh's brotherhood of dedicated young men become the elite Granite Mountain Hotshots: a fully certified, Type-1 team of firefighters for the city of Prescott, Arizona. Kenneth Chisholm that his highly trained, Type-2 municipal fire-fighting team won't be the one in the front line if a fire threatens their town, the committed supervisor, Eric Marsh, pushes his crew to their limits. All this is put to the test in 2013 with the notorious Yarnell Hill Fire that will demand efforts and sacrifices no one can ignore. In doing so, all the men, especially McDonough, are changed as new experience and maturity is achieved in fire-forged camaraderie. Along the way, the new team meets the challenge and the hailed Granite Mountain Hotshots are born.

To that end, Marsh needs new recruits, which includes the young wastrel, Brendan McDonough, to undergo the rigorous training and qualification testing for the most dangerous of fire fighting duty. To change that, Marsh gets approval from the Mayor to attempt to organize an unprecedented certified municipal-based Hotshot crew for Prescott. In 2007 Prescott, Arizona, Eric Marsh of the Prescott Fire Department is frustrated fighting forest fires when the Type 1 or 'Hotshot' front line forest fire fighting crews from afar overrule his operational suggestions to his area's sorrow. Based on the true story of the Granite Mountain Hotshots, a group of elite firefighters who risk everything to protect a town from a historic wildfire.
