Pete Sandich is an
aerial firefighter whose excessive risk-taking in the air deeply troubles his girlfriend, Dorinda Durston, a pilot who doubles as an air traffic controller for the firefighters. It also concerns Pete's best friend, Al Yackey, a fellow firefighter pilot. After yet another risky and nearly fatal flight that Pete casually shrugs off, Al suggests he accept a safer job training firefighting pilots in Flat Rock, Colorado. He refuses until Dorinda tearfully confronts him, confessing her perpetual fear and anguish that he will be killed. Pete relents and tells her he will take the training job. Pete flies one last mission, despite Dorinda's gloomy premonition. During the firebombing run, Al's engine catches fire and is about to explode. Pete makes a dangerously steep dive and skillfully douses Al's engine with a fire-retardant
slurry, saving him. As Pete struggles to regain control from the dive, he flies directly through the forest fire, igniting his engine and causing the aircraft to explode. Pete strolls through a burned-out forest. Coming to a small clearing, he meets Hap, who explains Pete died in the explosion and now has a new purpose: As spirits did for him during his lifetime, he will provide
Spiritus ("the divine breath") to guide others who will interpret his words as their thoughts. Although time is non-linear from Pete's perspective, six months have elapsed in the real world and Al wants a grieving Dorinda to move past Pete's death. He takes her with him to Colorado to work at the flight school where Pete is to lead pilots who will be training to fight fires, one of which is Ted Baker. More months pass and, to Pete's anguish, Ted falls in love with Dorinda as she begins emerging from her year-long mourning. Pete attempts to sabotage the budding romance, but Hap reminds him that his life ended; he was sent to inspire Ted but also to bid Dorinda farewell. Ted, with Pete's inspiration, plans a dangerous rescue mission for trapped firefighters. Unable to bear another loss, Dorinda takes his aircraft to do the job herself. Pete, unseen by Dorinda, fails to dissuade her. However, with Pete's guidance, she can save the firefighters who are trapped on the ground. On the return flight, Pete tells Dorinda everything he wants to say in life. Dorinda makes an emergency
water landing in a lake. As the sinking plane's cockpit floods, she seems reluctant to escape. Pete appears before her and, offering his hand, leads her to the surface. As Dorinda wades ashore, Pete releases her from his heart, allowing Ted to be in her life. Emerging from the lake alone, Dorinda walks back to the airbase where she accepts Ted and embraces him. Pete appears, smiles, and walks in the opposite direction to assume his place in the afterlife. ==Cast==
