Zack and the gang must beat rival club North Beach in volleyball, so Zack can win a deal on Carosi's car. They go through several sixth team members until Stacey steps up to play in the tournament.
The gang tries to raise money for the senior prom, Zack tries to get Kelly as his date, and Screech tries to find any date.
Zack is one credit short of graduating. He dances in Swan Pond to get the credit. Screech lets Jessie be the valedictorian, even though he earned it all before the gang finally graduates.
