In an attempt to find out who Kelly wants to take to a dance, Zack and Screech bug the girls' sleepover party and the girls get revenge.

When Zack finds out that the elected student council president gets to leave school for a trip to Washington D.C., he runs against Jessie.

Zack's plans of winning over Kelly Kapowski on the first day of high school are foiled when new transfer student, A.C Slater, also competes for her.

Jessie turns to caffeine pills to keep up with her studies and her new singing group, Hot Sundae.

When his friends forget his birthday, they try to throw him a late surprise party. Screech, upset that his friends didn't remember, takes advantage of his new hall monitor position and makes it difficult for them to plan it.
