Synopsis
The film opens in 1917 Alaska with Leonhard Seppala winning the Sweepstakes Race for the third time in a row. However, things change for Leonhard when his wife Kiana dies after giving birth to their daughter Sigrid, leaving everything up to him.
In 1925, in Nome, Alaska a child begins to cough during a ceremony in the village church. This passes without being noticed by Dr. Welch, but when other children start coughing as well, he realizes something is wrong and decides to visit some of them. When he realizes it's diphtheria, he immediately looks for the antitoxin, but in vain. Welch then decides to warn the mayor of the town and so a quarantine is triggered for the town. All the neighboring towns try to send the serum to Nome, but the snowstorm prevents the planes from flying and the frozen sea does not allow the ships to leave. The mayor then calls all the mushers and tells them that in Nenana, the nearest town to Nome, they have the serum but that it will be necessary to create a transfer with which to get the antitoxin. Seppala initially doesn't want to leave, because Sigrid has only him in the world, but then Constance, one of the nurses at the hospital and a very important figure for Sigrid, convinces him to leave. After an extreme effort, the antitoxin finally reaches Nome, but Leonhard has no more strength and is about to die. In a dream, however, he has a vision of Kiana who tells him not to give up and to return to his daughter. Leonhard wakes up in his bed at home, ready to start living his life again and spend it with Sigrid and Constance.
Historical accuracies between the film and actual events
In the film, Leonhard Seppala's wife and Sigrid's mother is an Inuit native woman named Kiana, whereas in reality, Seppala's wife and Sigrid's mother was really Constance. The film also portrays Constance as the church director of the children's choir, one of the nurses in Nome's small hospital, and Dr. Curtis Welch's daughter, as well as becoming Seppala's second wife and Sigrid's stepmother at the end of the film. Kiana was a fictional character made up in the film.
Just as portrayed in the film, Leonhard Seppala and his friend Gunnar Kasson both worked for the gold-mining company in Nome, as well as the fact that Seppala raised a large kennel of Siberian huskies on the sideline. Also, both the film and real events portray Togo as Leonhard's favorite lead dog.
Balto and Togo are portrayed differently in the film than in real life. In the film, Togo is a gray-and-white Siberian husky and Balto is a large black-and-white Alaskan Malamute. In reality, Togo was a mixture of black, gray, and brown in color, while Balto was a black Siberian husky with a white bib on his chest, a long white sock on his right leg, and a short white sock on his left leg.
In the film, only two children, two Inuit girls named Mary and Akina, died from the diphtheria epidemic before the antitoxin arrived. In reality, a total of seven children died from diphtheria before the epidemic was lifted, including seven-year-old Alaskan Eskimo girl Margaret Eide, three-year-old Billy Barnett, and six-year-old Inuit native girl Bessie Stanley.
Just like in the film, the relay of 20 mushers and their sled dogs did deliver 300,000 units of diphtheria antitoxin to Nome in six days. However, the antitoxin supply was a small amount and could only keep the epidemic at bay until a larger shipment arrived. What the film doesn't mention is that another 1,100,000 units of serum were gathered and shipped to Alaska, where a second relay of dog mushers and their teams picked it up and delivered it to Nome in another six days. The diphtheria epidemic was not immediately averted as is portrayed in the film, but it was finally lifted by February 15, 1925, four weeks after the epidemic had begun.
"Wild Bill" Shannon was the first musher in the first relay to pick up the serum in Nenana, but he did not arrive in Whiskey Creek as the film portrays. He did pass off the life-saving serum to Dan Green in Tolovana after travelling more than 50 miles through a freezing Arctic storm and losing four of his nine sled dogs in the process. Dan Green drove his team of sled dogs from Tolovana to Manley Hot Springs, where he passed the antitoxin off to the third musher in the relay, Johnny Folger. Charlie Evans, the twelfth musher in the relay, received the serum in Bishop Mountain from the previous musher George Nollner and carried it thirty miles down to Nulato, losing his two lead dogs in the process to the bitter cold.
Leonhard Seppala and Gunnar Kasson did not meet the last fifty miles of the journey nor did Seppala pass the serum over to Gunnar. After carrying the life-saving serum more than ninety miles from Shaktoolik and crossing the treacherous Norton Sound, Seppala arrived in Ungalik and passed the antitoxin over to Charlie Olsen, who carried it twenty miles from Ungalik to Bluff. Charlie then passed the medicine over to Gunnar Kasson, who carried it the last fifty-three miles from Bluff to Nome.
In the film, Leonhard Seppala's team of dogs consisted of seven dogs and Gunnar Kasson's team numbered eight dogs. In reality, Seppala's team numbered thirteen Siberian huskies with Togo as the lead dog and a second dog, Fritz, as co-leader alongside Togo. Gunnar's team also numbered thirteen huskies from Seppala's kennel and his lead dogs were Balto and a brown-and-gray husky named Fox.
The film omitted two important events in Gunnar Kasson's and Balto's journey from Bluff to Nome. The first event was that during the start of the journey, Gunnar's sled tipped over against the strong Arctic winds and dumped the serum into a deep drift of snow. Kasson dug through the snow, retrieved the serum, and reattached it to the sled again before continuing on his way. The second event occurred when Gunnar and his dog team arrived in Point Safety, where the serum was supposed to be handed over to the last musher of the relay, Ed Rohn. But Ed Rohn, believing that Gunnar was not going to make it through the blizzard, had fallen asleep and left his dogs unharnessed and locked up in the barn. Gunnar had no choice but to continue on his journey to Nome, where at 5:30 am on February 1, he and his dogs arrived in Nome with the life-saving serum.
