Jaz lives in the small northern community of Destiny and is a new member of the Junior Canadian Rangers. Her divorced parents argue a lot, and Jaz hopes if she wins a dog-mushing derby, they will be so proud of her they will stop arguing. But the derby would be a lot more fun if she wasn't paired with Colly, an older boy who is a more experienced JCR. On the derby trail all Jaz's newfound skills, her will to survive and her ability to get along with Colly, are put to a life-and-death test.
