As Senior Prom approaches, the teachers use the dance to relive their glory days. Fairbell and Abbey's "friend date" is a disaster, Principal Quinn has the worst night of his life, and Shoemaker's looming divorce leads him to get his angry band back together.

A former student leaves a threatening letter for Principal Quinn, Loren, Shoemaker and Fairbell and they quickly realize they're stuck in the middle of his sick, murderous game. Trapped in the school at night, with corpses piling up, the teachers must fight for survival.

Shoemaker is tormented by a disturbing sex dream that the drama teacher advises him to act on; Fairbell befriends the new school police officer.

The guys come to school drunk on the day Superintendent Carson promises to fire the worst teacher, and Loren maintains a buzz in order to save face.

After leading the JV Girls Volleyball team to the State Championship, Fairbell gets benched when the PTA appoints a new coach. Plus, Shoemaker takes asst. coaching a bit too far, and Loren schemes for a shady game sponsor.

After a lice outbreak at Smoot, Loren takes matters into his own hands and commands the "hot zone." Shoemaker and Tammy square off in a haircutting contest, while Abbey revisits some not-so-fond high school memories.

When the junk food vending machines get yanked by the PTA, Shoemaker and Abbey go to extreme lengths to get them back. Loren faces off with his old home-ec teacher, while Fairbell's sexual orientation is uncovered with the help of a peculiar videotape.

The teachers protest poor working conditions by going on strike. Shoemaker and Abbey butt heads over who's the real strike leader, and Loren and Rod tailfate the event... leaving Quinn and Tammy to man the understaffed school.

Principal Quinn tasks the guys with helping a shy kid wih the student election, but they do their jobs a little too well and unwittingly create a monster. And Abbey and Quinn have a fight over Smoot High's debate practices.

When the school bully begins picking on some of the teachers at Smoot High, the teachers exact a terrible (and stupid) revenge...and even the librarian gets in on the action!
