When WDFW officials receive an anonymous tip that poachers might be taking young falcons and eagles from nests around eastern Washington and shipping them to a Russian oligarch, Washington State fish and wildlife officer Luke McCain and his colleagues must go to new heights to save the federally protected raptors.

Meanwhile, domestic animals are going missing in the region, and Luke investigates the gruesome remains. As details of the animals' mysterious deaths emerge, rumors explode that a mystical creature-the ever-elusive bigfoot-may be responsible. Thinking a more plausible explanation is likely, Luke endeavors to unravel the clues leading authorities to whoever, or whatever, is killing the animals before bigfoot mania overruns the region and more beloved animals are slaughtered.
