Champion musher Jessie Arnold has been out of racing for a number of years, ever since she incurred a devastating knee injury. Now she's ready to get back into shape for this year's Iditarod. While taking her team on a practice run down a local trail she takes a snowy bump that's never been there before. It turns out to be a snow-shrouded body.
Now, Jessie and her boyfriend, Alaska State Trooper Alex Jensen, are back chasing criminals. And the hunt is on for the killer of a supposed earthquake victim-whose death turns out to actually be a murder.
