After receiving a call from the newly appointed chief of the New Mexico State Police, ex-Santa Fe chief of detectives Kevin Kerney is thrown into an investigation of a small-town cop-killing no one has been able to solve. His only lead: a homeless schizophrenic's ramblings about rape and an uncharted place called Serpent Gate. Meanwhile, back in glitzy Santa Fe, priceless art is stolen from the governor's offices and a beautiful young blonde is murdered in a millionaire's mansion.
