The files on a series of murders find their way to the Unsolved Case Review Division of the Tucson Police Department, better known as Cold Eyes. Charles Ewing, a brash young corporal and SWAT sniper finds himself in the center of an internal investigation. Teamed up with Bob Earp, an aging and cynical detective, they make up Cold Eyes. Joined by a beautiful attorney from the D.A.'s office they follow the thread that binds the cases together and leads them to two men, identical twins born in the hill country of western Arkansas. As the Cold Eyes team draws closer to the surprising answer to the puzzle, Ronnie and Kenny Loker lash back and make one last desperate attempt at freedom. The breathtaking climax pits Bob Earp against them and against time in the loneliness of the desert night to prevent Maria Rodriguez from becoming their next victim.
