When the body of a young woman is discovered in a derelict cottage in Los Angeles, Robert Hunter is thrown into a nightmare case. The victim suffered a terrible death, and on the nape of her neck has been carved a strange double-cross: the signature of a psychopath known as the Crucifix Killer.

But that's impossible. Because two years ago, the Crucifix Killer was caught and executed. Could this therefore be a copycat killer? Or could the unthinkable be true? Is the real killer still out there, ready to embark once again on a vicious and violent killing spree, selecting his victims seemingly at random, taunting Robert Hunter with his inability to catch him?

Hunter and his rookie partner, Garcia, need to solve this case and fast.
