Rachel is frustrated with her new job, and even more frustrated when she finds out that Shawn parked in her reserved space. Rachel vows to return the favor despite Topanga warning her about starting a prank war with the masters—Cory and Shawn. Cory and Shawn strike first by parking Rachel's car in her room and setting her alarm to wake her up to see it. Rachel goes to Mr. Feeny in attempt to get Cory and Shawn in trouble, but Mr. Feeny is too busy laughing and wondering how they did it. Angela takes sides with Rachel and they tell Cory and Shawn that the war is on.
Next the teams are chosen: It's Cory, Shawn, and Topanga taking on Rachel, Angela, and Jack. Eric decides to remain neutral when neither team selects him. Rachel's team's first prank is putting super glue on Cory, Shawn, and Topanga's seats in Mr. Feeny's classroom. Next honey is dumped on their heads from above and a bear enters the classroom. Eric is the only one who comes to his senses telling everyone to quit the prank war before someone goes too far, a message that they all ignore.
Cory and Shawn refuse to be outdone, so their next prank is putting up a life-size poster of a half-naked Rachel in the student union. Rachel gets really upset and Angela can't believe what they did either. Topanga walks in and is not only angry that they hurt Rachel's feelings, but also angry that they didn't tell her about it first. This prompts a serious argument, and they all begin verbally attacking each other every time they see one another.
At this point, the only person who hasn't got hurt is Eric. That is until he steps in and attempts to help his roommates Shawn and Jack make-up. Jack gets angry and tells Eric that he didn't get picked on a team because nobody wanted him.
