Charles Rawden is a man of violent temper, which is shown in a quarrel with his friend, Tom Wallace. Nellie, to whom both men are paying court, accepts Tom as the more desirable life partner. Rawden's temper is uncontrollable; he becomes involved in a saloon fight and almost kills his man. Nellie, with her husband, goes to Alaska. Rawden, who is now called "The Sky Pilot," is engaged in missionary work in the same place; he accomplishes much good, and makes many converts to the Cause. An epidemic of disease breaks out among the people. "The Sky Pilot" is called to help in many a cabin and home. His friend, Tom Wallace, is stricken down with the disease. Charles insists upon sending Tom to the nearest military outpost and persists in sending him there on his own dog sled, while he goes afoot. Journeying through the snow-clad country in the intense cold, he is overcome with that feeling of numbness. He falls prostrate and helpless, where he is found by "White Bird," the Indian girl. She carries him to the Indian village, where he is revived, and after complete recovery takes up the trail to the outpost, to which his friend, Tom Wallace, had been taken. Arriving at the army headquarters, he learns of his friend's death and burial. Two years later "The Sky Pilot's" lifelong romance has a happy ending; he marries Nellies, tom's widow.
