In Eastern Washington, a group of young ranchers form a secret alliance to hunt the gray wolves that are continually preying on their herds. Using a hidden site on the dark web, they coordinate illegal kills, leaving a trail of poached carcasses and baffled authorities. Miles away, a wealthy environmentalist who helped reintroduce the wolves to the region decades earlier reads about the so-called wolf-killing Renegades in The Seattle Times. Furious, he hires hackers and fixers to unmask the people slaughtering his wolves. When names surface, he takes justice into his own hands murdering one Renegade and setting his sights on the next. But Washington State Fish and Wildlife officer Luke McCain is already on the trail. He identifies the next target and races to warn him. As the killer closes in, a final confrontation plays out in the cold wilderness, where a wounded man faces the very predators he once vowed to protect. And where the law of nature is more brutal than any courtroom.
