Output: Cliff Mason, a veteran foreman of the Forest Services smokejumper unit, is called out with a crew on a fire, despite the fact that they have not rested in three days. Accompanied by R. A. Pop Miller and four other men, Cliff leaves the smokejumper base at Missoula, Montana to parachute into a nearly inaccessible area of Bugle Peak. Hours later, at base, superintendent Richard Dick Dryer becomes worried because Cliff is not answering radio calls. The next day, after the fire crowns, Dick flies by helicopter into the area and is stunned to find only Cliff, in shock and wandering through the devastated region. Cliff is rushed to the hospital, where he gradually recovers, although he cannot remember how he got separated from his men, or why he was the only one to survive. Upon his return home, Cliff is greeted by Pops son Ed, who is also a smokejumper. Ed expresses genuine concern for Cliff, but Cliff, sensitive about his lack of memory and worried that he might be responsible for his crews deaths, becomes antagonistic. A board of review conducts a hearing into the matter, and Cliff grows increasingly defensive after several grueling days of repetitious questioning. Cliffs paranoia grows that he might be thought a coward who deserted his men despite the assurances of his devoted wife Peg and Dick, who lets him return to work only as supervisor of training. Ed continues to grill Cliff, asking him how he might have come to be in the protected rock slide area that was the only possible place of survival when the bodies of his crew were found on an exposed ridge across the valley. Eds suspicions escalate and Cliff reacts even more bitterly. One night, an emergency crew is called out to repair downed transmission lines, and when Cliffs longtime friend Boise Peterson is shocked by a live wire, Cliff saves him. Ed pointedly remarks that it was not necessary for Cliff to prove his bravery. Cliff is cleared by the board of review but confides to Peg that he is plagued by doubts about his courage. Later, Dick shows Ed a watch, mistakenly sent to another mans family, that Ed recognizes as his fathers. Upset again, Ed confronts Cliff with the watch, and jogs his memory. Cliff recalls that when the fire began to race along the treetops, all of them had reached the rockslide where he urged them to lie down in the crevices. However a burning snag fell on the rockslide and the crew continued running. Cliff attempted to stop Pop, pulling off his watch and ID tag as they grappled, but Pop knocked him into a crevice that protected Cliff from the worst of the fire. Ed furiously accuses Cliff of deserting his men and goes AWOL, parachuting from a private airplane onto Bugle Peak, where he finds Pops identification bracelet on the ridge, not on the rockslide, where Cliff says he saw Pop last. Believing he has obtained proof that Cliff abandoned his men on the ridge, Ed returns to base, only to discover that Cliff and another team of men have been sent to fight a fire in Carson Canyon. Confronting Dick with the ID tag, Ed accuses Cliff of killing his father, and Dick fires him from the smokejumper unit for going AWOL on a personal grudge. In Carson Canyon, Cliffs crew brings the fire under control but weather conditions threaten a reburn, prompting Cliff to request more men and equipment. Ed joins the smokejumper reinforcements without authorization and at Carson Canyon tracks down Cliff, scouting the fire that now has them trapped. After losing his head and trying to kill Cliff with the axe end of his Pulaski, Ed breaks his leg when he tumbles down a slope as they fight. Cliff returns to the crews anchor point to organize the men, sending three with heavier equipment to bring in Ed. Cliff orders the others to dig foxholes, knowing that burying themselves and allowing the fire to pass over them is their only hope for survival. The men protest but grudgingly comply when Cliff insists. Ed is surprised to discover that Cliff is responsible for his rescue, and when he is brought back to the anchor point, the crew panics and starts to flee. Ed sees Cliff knock down Boise to quell the panic and realizes Cliff was telling the truth about Bugle Peak. After the fire has passed, all of the smokejumpers have survived and Ed, reconciling with Cliff, sheepishly grins and asks for a cigarette, inspiring Boise to do the same. When Dick realizes the entire crew has survived, he reinforces Cliffs men from the air as an even larger ground force with bulldozers swings into action.
