Strange lights are spotted over the high desert of northern New Mexico. Unmarked helicopters fly to and from Archuleta Mesa on the Apache Reservation. A ranch foreman is found dead. And, after nearly a decade, livestock are being killed and mutilated, again. Deputy Cliff Lansing is running for his first term as sheriff. In the midst of his campaign, the one-time rancher has to deal with divorce, the loss of a friend, and the gaggle of UFO enthusiasts who have descended on San Phillipe County. Lansing joins forces with Ned Koteen, the newly appointed Apache Reservation Police Chief, to investigate government coverups, conspiracies, and murder. While Koteen struggles with tribal secrets, Lansing has to fight his own family's demons.
