Silence. Dead Silence.
Two men, brutally murdered on a remote island, greet Dave Trask on his first day as sheriff of Lake County, Minnesota, a wild place stretching from the shore of Lake Superior to the Canadian border. The murders are vicious, but Trask finds himself impressed with the stealth of the killer who seemingly walked up to his victims unnoticed.
The dead men were guests at a small fishing resort. A guest at another resort is soon murdered, the tourism business so important to the county now on edge, fingers being pointed from small resort owners to the owners of the large corporate camps. The fragile relationship between the white camp owners and their Native American guides is also stretched thin when evidence points towards a guide.
Trask is under pressure from all sides, including the county board, to stop the killer, but he is held back by an inexperienced staff. Dave calls on his identical twin brother Don, special agent for the Minnesota Bureau of Criminal Apprehension, to help him hunt the seemingly invisible killer through the wilderness. Little did they know they would soon be the hunted.
