Randy Johnson, a former green beret platoon leader in Vietnam, has now settled into the peaceful life of an Idaho rancher. It holds a kind of a magic, a new freedom, a relief from a cunning invisible enemy left behind in the dangerous jungles of Vietnam. He’s good with a gun, fast on a horse and as tough and smart as the next man, but he’s about to meet a new enemy more cunning and illusive than the one he left in Vietnam. Idaho’s television stations issue Breaking News alerts almost hourly providing the latest gruesome statistical details of newly discovered mutilated cattle—many found on ranches adjacent to Randy’s—and that concerns Randy. Five hours later the mutilators strike Randy Johnson’s isolated horse ranch—and all hell breaks loose. It is up to law enforcement to find the answer and solve the mystery. Can they do it?
