Maria will do anything, and does practically everything, to find her younger brother Tino – a lazy klutz whose only interests are girls and Gilligan's Island – a job at the mall. Because he keeps botching the interviews (even wearing jeans and a red T-shirt to one!), she has to do all the work for him. Even that doesn't help because, if there's a way to get himself fired, he always finds it before the day is up. Finally, Maria goes over her boss's head to get Tino a job with her at the Teen Machine club. There, being Tino, he costs Maria her job (to say nothing of his own)... and may cost the boss her license to boot. Meanwhile, Screech finds it difficult to hold down two jobs—mall security guard and assistant to Mr. Belding — and is forced to give up one.

To everyone's amazement, she says yes. The couple is getting along great, but the entire gang (except for Liz) feels that Claire may have an ulterior motive of using Screech to get a permanent job at Bayside, since he's close to Mr. Belding. They tell Screech their suspicion, and he believes it. He tells Claire off and breaks up with her, despite her pleading that she wouldn't use him like that. Once Claire gets a job at Willowbrook Academy, but is still unhappy, the gang realizes Liz was right and they made a huge mistake. They come up with a plan to get Screech and Claire back together.

Maria is reunited with her former Valley High classmate Tony Dillon, four years after he stood her up (she thinks) at their middle school prom. Although he would love to patch things up with her, she makes this impossible by spreading vicious lies and rumors about him – which not only costs him his job at The Max but drives his own football teammates to seriously injure him during practice. Finally, the truth comes out: Tony ditched her at the prom because he couldn't afford a tuxedo; and broke their more-recent date because his interview for the Max job (from which she got him fired) ran overtime... Meanwhile, Eric and Nicky and Katie try to console Liz after Ryan's departure, although Liz has long since gotten over it; predictably, her friends' good intentions pave a road to disaster... Elsewhere, Screech tries to convince Mr. Belding's son Zack that his dad is cool – by staging scenarios that will make Mr. Belding seem strong and/or tough.

Liz's new boyfriend, Travis, convinces her to do whatever he wants...like skipping out on her friends and responsibilities. Ultimately, he asks her to skip out on the big swim meet and see Pearl Jam.
