Abby loves the thrill of danger that comes from attending masked sex parties, but it's not long before she finds herself feeling something more than lust for fellow partygoer, Jake Winters. When someone at one of the parties is murdered, and Abby learns that she and Jake were the last two people to be seen with the murder victim, she begins to wonder if Jake could possibly be the murderer.
Abby can't deny her feelings for Jake, and when he shows up at her apartment, Abby doesn't hesitate in letting the potential murderer in. When Jake tells Abby an almost-unbelievable story about werewolves, an old werewolf legend, and how it's all connected to the murder, Abby becomes wary. Can Abby trust Jake, or will her feelings for him only prove to endanger her?
