Grandview, U.S.A.

Eighteen-year-old Tim Pearson, a soon-to-be graduate of Grandview High School, wants to go to Florida to study oceanography. Tim's father, Roger Pearson, loans Tim his brand new Cadillac to go to the Prom with his date Bonnie Clark. Later, while parked near a stream, Tim and Bonnie are making out in the Cadillac, when they feel the car moving, only to discover that the car is falling into the stream. Tim and Bonnie walk to "Cody's Speedway" to get a tow truck, Bonnie calls her father, who is so angry about the accident that he punches Tim. Mechanic Michelle "Mike" Cody comes to Tim's defense, and has Ernie "Slam" Webster, a local demolition derby driver, tow the car, taking Tim along. Slam stops at the bowling alley to see if his wife Candy had been there, but she wasn't.
