Spider is a young man who makes a meager living repairing CB radios and spends his spare time volunteering with REACT International.

Spider's former fiancée Pam (Electra) is a cheerleading coach and physical-education teacher who conducts erotic conversations over the CB with teenage boys.

After Spider's activities with REACT are disrupted by a gang of local kids holding a frivolous conversation on Channel 9, which is reserved for emergency communications, he decides to embark on a singlehanded nationwide crusade to shutter illegal CB stations, such as those using unlawful linear amplifiers.

Spider's targets include the Red Baron, a neo-Nazi who uses a high-powered CB base station to broadcast white-supremacist hate speech, and the Hustler, a teenage boy who reads pornography aloud over the air.

Spider and a partner from REACT begin a spree of cutting antenna cables, intimidating offenders by visiting their homes and claiming to be Federal Communications Commission (FCC) officials in the hope of cleaning the CB airwaves.
