Halloween. A group of friends gather at a mansion and decide to play a game. When one of them disappears and a large pool of blood is found on the grounds, San Francisco homicide inspector, Mac Jackson, is called out to investigate. Two days later, the body is discovered. As Jackson questions the guests, he uncovers old hostilities, secretive pasts, and the victim’s ties to another unusual death. At the center of it all is the lingerie bar, where the victim once worked. Are the girls in some sort of danger? Who is the thug with the scar? His best chance at solving the case hinges on an uncooperative source and Jackson must work fast, before it’s too late and his source disappears.
