Documentary recalling events of January 28, 1925, when dog sleds played a significant role in transporting a diphtheria antitoxin to Nome, Alaska, following an outbreak in the town. The programme reveals how, because of the freezing weather and undeveloped aviation technology, this ancient means of transport - consisting of more than 20 men and at least 150 dogs, including the canine icon Balto - managed to save an entire community from disease and death
