Oddball cable installer Chip Douglas (Jim Carrey) attempts to strike up a friendship with customer Steven Kovacs (Matthew Broderick) by offering him premium channels at no cost. When Steven rebuffs Chip's frequent need for companionship, Chip goes from a mildly eccentric acquaintance to a full-fledged psycho stalker. Though it's increasingly apparent to Steven that the cable guy is dangerous, convincing his friends, family and the authorities of that is another matter entirely.
