A group of doctors go on a camping trip in the deep forests. There they have fun. They brag about each other's fields n at the same time their conversations revolve mostly around medical malpractices, unethical surgeries n they even mock patients except for Harry (Hal Holbrook). Unaware to them, a stalker has been hearing their conversations. Now the place they had gone is in the middle of nowhere according to their pilot who dropped em earlier. So it seems our stalker might be not just another ordinary citizen. Later the doctors realize that their boots are stolen n someone has left a deer carcass on a stick with a snake around it, the symbol similar to the Staff of Aesculapius, the symbol for the American Medical Association. So this confirms us that the stalker is aware of the doctor's history from overhearing their conversations. The stalker leaves x-ray taken from a military hospital, medals n discharge papers, a message meant for doctors with callous attitudes regarding their trade. The doctors soon realize they are being hunted by an ex army person who first wants to degrade them before killing them but our Harry, a war veteran himself, won't let the madman enjoy their degradation.
