Nestled inside a private mountain community are The Gates. The image of perpetual suburban bliss, each street is lined with perfectly manicured homes protected by the massive iron gates, but a dark and delicious secret is buried just beneath the surface of this picturesque neighborhood.
The Monohan family moves into a new home in an exclusive community called The Gates; things become complicated when the father, the new chief of police, must investigate neighbors in a missing-persons case his first day on the job.
Former Chief of Police Phelps was killed by a single gunshot wound to the back of the head. Things like that just don't happen in The Gates. Frank Buckley wants Nick to do his best to manage the situation. But the new chief isn't interested in a management position; all he wants to do is find the person who killed a cop.
The policy at The Gates is that the police cannot enter a house without owner permission. But when a silent alarm is tripped at the McAllister home, Nick Monohan can't wait for an invitation.

At another one of those classy, cliquey social events we've come to love at The Gates, Ben McAllister and Simon Ford get into a little scuffle about lawn sprinklers. There's always been bad blood between these two, probably because Ben's a vampire and Simon's a werewolf. And vampires don't like when werewolves set their sprinklers to sprinkle while they're walking to their car. Hey, humans don't like it either.
Special Agent Kat Russo of the FBI believes the target of a federal investigation is living inside The Gates. Robert Jessup is accused of financial fraud.

Ever have one of those days when a hideous, vengeful creature is trying to kill you from beyond the grave? Well, Nick Monohan is being haunted by Teresa, the woman who tried to kill him in "The Monster Within." Devon says Nick's nightmares will cease if he tries some of her special tea. Nick is reluctant to do so, because he doesn't trust Devon. The chief's a smart guy.
