Someone is out for revenge against Milt Kovak, sheriff of Prophecy County, Oklahoma. A sinister note is taped to the office front door, and a dummy found hanging in the interrogation room. If that wasn't disturbing enough, the brake lines on a deputy's car are cut, causing his wife to crash. Meanwhile, two friends of the mother of Milt's other deputy are taken to hospital, poisoned after eating her peach melba. It's not long before Milt and his team have a murder investigation on their hands. And if Milt doesn't find the killer soon, his own nearest and dearest could be next in line.
