Pulse (1988)

In today's world of modern conveniences, everything we rely on is run by electricity. But what happens if the power we take for granted turns against us? Old man Holger (Charles Tyner) knows. He claims electricity is a living presence, whose voice can only be silenced by getting rid of anything that can hear it. Bill Rockland (Cliff De Young), however, refuses to believe him. It must have been an accident when an electric spark ruptured the gas pipe that nearly killed Bill's son (Joey Lawrence). And it's surely a coincidence when his wife (Roxanne Hart) is severely scalded by their electric water heater. But when his own power tools attack him and an electrical fire turns their home into a blazing inferno, Bill realizes Holger may have been right after all, and perhaps the time has come to finally pull the plug.
