Former Bayside High pupil and current college student Samuel ""Screech"" Powers returns to his alma mater as an administrative assistant to Mr. Belding. A new student from Switzerland, Brian Keller, is attracted to Rachel. Rachel ruins her mom's $700 jacket and the gang helps her come up with a plan to replace it, a plan which makes Screech an unwitting participant.

Megan is running a blood drive and while contributing to it, Screech falls for the pretty nurse Penny Brady. Meanwhile the gang needs to find a chaperone for their camping trip. Brian comes up with a scheme to get Screech to do the job, but first he must get him a date with Nurse Brady.

The kids operate a booth at the Bayside Carnival. Bobby is threatened by a bully who likes Megan. For protection, he takes karate lessons from an unlikely teacher--Screech!

Screech is looking for more challenging responsibilities, so Mr. Belding makes him faculty advisor for the Bayside Breeze, the school newspaper which needs some livening up. The first big story is about the girls' swim team not being able to go to the tournament finals for lack of money. Screech gives his staff permission to skip Belding's PSAT review and other classes to work on deadline. Mr. Belding has to talk to Screech about him letting students miss so much work. Screech shuts down operations on the paper for a while and leads the PSAT review himself. After the test, the kids trick athletic director Mr. Doyle into admitting how he took money from the girls' swim team for use in other sports.

It's Bayside's prank day and everyone is playing tricks on each other. But it's no joke when Belding makes the mistake of inviting the new superintendent to Bayside. He cancels prank day but when no one listens it spells disaster for Belding.

It's time for the big game between fierce archrivals Bayside and Valley, and it turns out that Megan's new boyfriend is the captain of Valley's football team.

Lindsay can't afford to buy a birthday present for Tommy, so Brian and Bobby get ahold of the school's video equipment so she can make a video for a present. Meanwhile, Brian's sister Katie, and Tommy are falling for each other. Lindsay and Tommy are looking at the end of their relationship.

New transfers to Bayside include three students from arch-rival Valley High: R.J. ""Hollywood"" Collins, head cheerleader Maria Lopez and Ryan Parker, who stole Bayside's mascot the year before. The old gang greatly resents these newcomers. Ryan makes plans to date Lindsay, make Maria the head cheerleader and get R.J. to emcee the Welcome Back dance. The two groups fight so much that Mr. Belding makes them stay on separate sides of the gym at the dance and wear identifying badges. But before the night ends, the enemies all dance with each other. Also, Tommy D. is thinking of how to get back together with his old girlfriend, Lindsay.

Lindsay is nominated for Homecoming Queen, and so is Maria, even though she really doesn't want it, but she soon becomes competitive. Mr. B asks Rachel to help tutor star football player Todd Green to keep him eligible. She finds that Todd can grasp things she tells him very well, but he has great difficulty reading. An attraction develops between Todd and Rachel.

Meanwhile, the Homecoming Queen campaign has gotten heated with Ryan and Tommy working for Lindsay and R.J. becoming Maria's manager. The campaign gets dirty when Maria is accused of being a Valley High ""traitor."" Todd fails to complete the test he's been studying for. Rachel tells Mr. B. about Todd's problems. The principal suspects Todd might have a form of dyslexia. Todd is mad at Rachel at first but things get straightened out and Todd passes a verbal makeup test. Lindsay and Maria stop the dirty campaigning and vow that whoever wins will give the crown to the other girl. Who wins? Rachel, as a write-in!

Bayside joins the High School Television Network and the gang produces a show with Screech as faculty advisor and director. Unfortunately, the first edition of ""Bayside Live"" is a disaster. Mr. B. gives the group one more chance and they come up with a concept based on the show ""Tough Copy,"" which Mr. Belding likes.

R.J. catches the eye of a talent agent, Gavin Malone, who promises to make him a big star. But R.J. is the one forking out the money, giving the agent hundreds of dollars for photos and ""expenses."" Maria is suspicious of the agent and goes snooping in his office, where she finds that Malone is bilking other clients, too. Meanwhile Mr. B. and Screech find out the TV show is planning to fake an earthquake on the air and they pull the plug. Ryan plans to expose the agent. He has R.J. tells Malone that he's dumping him for a new agent, ""Hal E. Wood,"" who is in reality Screech. Malone tells ""Wood"" that the two should combine their talents to exploit more young clients, thereby r

Tommy has fallen for a girl named Nicole, but he's afraid she's too classy and cultured for him. He confides to Rachel that he's trying to write poetry for Nicole. Tommy reads a poem of Rachel's in class and gets an ""A."" Nicole is impressed, and Tommy makes a date with her--at the opera! Ryan schemes along with R.J. to make Tommy appear cultured, hoping to impress Nicole's father so that they can get Boys II Men tickets from him (he's the manager of the L.A. Amphitheatre) and take out Lindsay and Maria. Tommy is now nervous about meeting Mr. Miller and feels like a phony.

Nicole tells Rachel and Lindsay how cultured ""Thomas"" is, which causes the girls to bust out laughing. When Nicole finds out from them that Tommy didn't write the poem, she's mad at him for deceiving and using her and doesn't want to see him. Meanwhile a school ballet production is called off, disappointing Nicole. Tommy volunteers to dance in the production so Nicole's father can see her perform, and he recruits the

Screech thinks he's won the lottery.
