A serial killer is transformed into a computer virus out to destroy more than your hard drive in this sci-fi thriller. Terry Munroe (Karen Allen), a single mother, is looking for a gift for her boss and visits a computer store, where one of the employees demonstrates a hand-held scanner than can transfer the information from her address book into a software program that will store the information on her PC. Unknown to Terry, one of the employees of the store is Karl Hochman (Ted Marcoux), known in the press as "The Address Book Killer," who likes to steal other people's address books and murder all the people listed within, including the book's owner. Terry accidentally leaves her book behind at the store, and Karl lifts it, but as he drives to her house to strike her off the list first, he is injured in a serious accident and taken to a hospital. While Karl is being given a CAT scan, lightning strikes the building and Karl is transformed into a series of electrical impulses that can travel as computer code from one system to another, or as current through power lines. Soon Terry begins to suspect something is wrong as her friends succumb to attacks by microwave ovens, hot-air blowers, and other household objects. Terry and her computer-savvy son, Josh (Wil Horneff), realize that they're at risk after Karl appears in Josh's virtual reality games; it's up to Bram Walker (Chris Mulkey), a brilliant hacker-turned-computer maintenance technician, to isolate and destroy the Karl virus before it can kill again. The film's soundtrack features such hip-hop stars as D-Nice and Too Short, Schoolly-D, Grandmaster Slice, and Kool Moe Dee.
