The 35th running of the Iditarod delivered one of the most gut-wrenching, inspiring odysseys in the history of the race. Ferocious ground storms forced some of the fiercest and most experienced competitors to leave the race entirely. This is the story of finishers who overcame incredible adversity to reach Nome: and the story of lucky number 13 and a team that set out to do something that had never been done before. This documentary captures the tale of a field of courageous athletes, up close and personal, that risked it all running "The Last Great Race on Earth"--a race that in 2007 was truly as tough as they come.
