Transfer student Tori is introduced in this episode, but Zack and Tori don't hit it off, and they are paired up for an ad project. Lisa alienates the Dance Committee before the Fall Ball.

If Zack can just get out of detention with Mr. Belding, he can win a trip to Hawaii. Instead the whole gang ends up in detention with him, trying to get him out.

The gang learn about the dangers of drinking and driving when, after getting drunk at a party, they get into an accident in Lisa's mother's car and try to cover it up.

Zack appears to have negotiated a great deal on class rings for the senior class, but it turns out he has been scammed. While he plots revenge, a misguided bet between Tori and Lisa leads to Screech falling for Tori.
