The Sackett family never had a chance. Attacked in their home by an intruder, the couple and their three children were slashed to ribbons, decapitated, eviscerated. One year later, a group of college students moves into the so-called "Whack-it House" on a mission not only to complete a senior project, but discover the identity of the killer and get justice at last. Luis, whose father was a police detective, has all the files on the case. Marc is a computer wiz, responsible for setting up and maintaining the surveillance equipment, computer and website that the group will be using. Deke, with his alpha dog personality, is the group's de facto leader. The guys are joined by Lynne, a sexy B movie actress now completing her media arts degree; Kim-Ly, a petite but scrappy Vietnamese martial artist; and Cody, a Native American student who senses early on that something is not right. Each night they re-enact one of the Sackett family murders, and each time something goes wrong. Tempers flare, blood flows and then the threatening phone calls begin. Soon, the group has more questions than they have answers. Who really killed the Sacketts and has he come back for more?
