As a couple drives down a freeway, a piercing tone starts to emanate from the radio speakers. The same sound can be heard coming from the other cars on the freeway and soon all cars begin to catch on fire then explode. A short time later, Team Knight Rider joins the crowds of officials th at have swarmed the scene of the disaster. TKR discovers anything carrying gasoline within a 25 mile radius, including a gas station, has been damaged. Trek (Nick Wechsler) takes a sample of fuel from a car in the area and TKR heads back to SkyOne.
