When a skier goes missing at Sun Valley's Galena Summit, Sheriff Walt Fleming quickly assembles his crack search-and-rescue team and heads out into the snowy night. Despite the treacherous conditions, Walt and his group, including deputy Tommy Brandon and Walt's best friend, Mark Aker, set off on skis, accompanied by highly trained search dogs. Within minutes, something goes horribly wrong: a shot rings out, and one of their team is dead. By morning, Mark Aker has disappeared.

Torn between professional responsibility and the desperate urge to find his friend, Walt is further challenged by an unexplained illness at a local water bottling plant that sends workers to the hospital and sets off biohazard warnings. Following threads of questionable evidence through the glitter of Sun Valley leads Walt to an unlikely - and darker - source, and reveals a crime played out on a much larger scale than he originally envisioned. Waist-deep in snow and knee-deep in lies, the life of his friend in the balance, Walt begins to suspect that the whole operation is controlled by people of great wealth and power, which leaves him where he started: out in the cold.
