RCMP Corporal Alex Houston, her fiancé Canadian Forces Captain Don Harrison, and her friend and partner Silver make a late-fall visit to a brand-new ski lodge high up in the Canadian Rockies. After only a short period of hiking and mountaineering in this idyllic setting, their vacation is threatened by a snow-storm that cuts off both power and access to the lodge. While they and a group of university students wait out the storm, a suspicious death puts Alex on the trail of a murderer.
