Plot:
Once inside a home, the entity gains control of everyday household appliances (such as televisions, thermostats, and water heaters), turning ordinary modern conveniences into lethal traps to terrorize and kill the occupants. The story focuses on 11-year-old David Rockland (Joey Lawrence), who is visiting his divorced father, Bill (Cliff De Young), and stepmother, Ellen (Roxanne Hart). After noticing strange electrical anomalies and witnessing the entities' deadly behavior, David tries to warn his family. True to the "technophobic" genre, his parents initially dismiss his fears until the entities' attacks escalate, severely injuring Ellen in a superheated shower and trapping the family inside a high-voltage domestic death trap.
