Following his suicide attempt, a loner and a loser who has never lived up to his father's expectations is sent to Alaska, where he subsequently enters the annual thousand-mile-long Iditarod Trail Race from Anchorage to Nome in memory of his Athabascan Indian friend who dies.

Jessie Arnold, Alaska's premier female "musher," must outwit a killer and survive the Alaskan wilderness if she hopes to win the Iditarod and its quarter-million-dollar cash prize.

When 15-year-old Emmylou arrives in Churchill, Manitoba -- the Polar Bear Capital of the World -- all she can think about is getting out of town before she ends up on the wrong end of a polar bear dinner. But things are rarely what they seem in the North and Emmylou's outlook begins to change -- fast. First, she meets Barnabas, a young Inuk who is training dogs for the gruelling Arctic Quest -- a sled-dog race held at the edge of the Arctic. That's...

Even though he is the runt of the litter from her father's prize sled-racing dog, ten-year-old Rachel plans to train her puppy to become a champion racer and determines to track him down when he mysteriously disappears.

Scooby-Doo follows the clues to solve the mystery of the missing sled dog.
