From CHiPs Online: Ponch and Jon chase two cars trying to run each other off the road. When they arrest the drivers, they learn that there are "Green Thumb Burglars" stealing shrubs.
Later they stop twins who drove through a stop sign. They claim to be famous psychics and predict trouble for Ponch. At Ponch's trailer, Ponch tries to get Jon lunch (tuna and beans) and Ponch cuts himself. Jon points out "Madame Butterball's" first prediction. At Central, Ponch has a run in with Getraer (making the second prediction come true). Getraer starts acting loopy when Jon mentions the plant thieves.
After the briefing, Ponch and Jon help a stuck guy out of his car after an accident. When a truck leaves the site, it's leaking gas. The back catches fire when it runs over a flare. Ponch tells the woman to keep the truck moving. Jon arranges a rendezvous with a foam truck. Ponch guides the truck into the foam and evacuates the driver to safety. Jon reminds Ponch about the prediction of an encounter with fire.
After visiting Central, Ponch notices something unusual driving a car. When they pull it over, H.R. Pufnstuf gets out. They make him walk (because his view was obstructed by the costume).
A few yards away, "Cal-Trans" landscapers are leaving a work site. Ponch and Jon chase them. When Getraer hears about it, he heads out and they dump their trees on him. The CHP corners them in a Drive-In lot. (Later seen in "The Return of the Supercycle") Getraer arrests them.
That night at Jon's apartment, Ponch learns that his date got engaged to a Sgt. Maloney...making the final prediction come true.
