A group of ravens scavenging on the carcass of a cow that has died from mad cow disease. The ravens then spread the disease to other animals in the area, including a farmer's dog.
The farmer, Clyde (Stephen McHattie), shoots the dog out of mercy, but the ravens attack and kill him. The ravens then begin to attack the townspeople, and soon the town is in chaos.
The sheriff, Wayne (Sean Patrick Flanery), and a group of townspeople barricade themselves in a diner, but the ravens continue to attack. The townspeople realize that they must find a way to kill the ravens or they will all be killed.
Wayne and a small group of volunteers go out to the farm where the ravens are nesting. They set the farm on fire, and the ravens are killed. However, the townspeople realize that the ravens are only a symptom of a larger problem: the mad cow disease that is spreading through the area.
