A grieving young mother and recovering alcoholic, Andi Nowak flees high above Canada's Arctic Circle seeking peace and solace, but instead finds intrigue, danger and romance. Haunted by memories of her daughter, Andi ventures north to the remote town of Inuvik and a challenging career at Tuktu Aviation. The discovery of a rich kimberlite pipe near the small community creates a diamond-mining frenzy, and more flying for Tuktu. When Andi discovers that their Twin Otter aircraft are being used for unauthorized purposes, her queries to the flight crew are first nonchalantly, and later violently, dismissed. Andi enlists the aid of her new friend, local gallery owner and dog-sledding enthusiast, North Ruben. Together they plot a scheme to trace the aircraft's mysterious movements, but their plan backfires with devastating - and deadly - results. Fear and anger spark Andi's ravaged emotions, and although she resists, her friendship with North heats with passion she never thought possible.
