At the Malibu Sands Beach Club, Zack wants to purchase a 1966 Mustang that the mean-spirited Mr. Carosi owns but refuses to sell it at a cheap price. So, Zack comes up with another nefarious plan: to have the gang form their own volleyball team for an impending competition with the rival North Beach Club so Zack can win the car, but if they lose, they'll all lose their jobs. Zack hires a tall guy, named Gary, to tip the scales in their favor, while Gary shows an interest in Kelly. But when Screech accidentally breaks Gary's foot and he cannot play, Stacey steps in as the replacement.
After discovering that the vintage Mustang he wants to buy belongs to Mr. Carosi, Zack convinces him to lower the price by claiming that the gang can win the annual beach volleyball match, though their chances of victory seem slim at best.
- With the Malibu Sands Beach Club on a losing streak against a competing beach club, Mr. Karose turns to the gang for help. Zack guarantees victory, and has Karose up the bet, which includes his vintage Mustang.
