Marcy organizes a "Toys for guns" campaign to get kids something else to play with than toy guns. Kelly has a post-graduation five-year reunion and is shocked to learn that the nerd she once stood up has become handsome and rich.

Bud and his three "frat bros," Hindu Achmed, fatso Hummer, and nerdy Barney, are set to leave for Spring Break in Fort Lauderdale in hopes of scoring some drunken babes. They have the tickets and the hotel reservation. That is, until Kelly, the naughty Fawn, the steamy Ashley, and the nerdy (but minus the headgear) Natalie, make them believe that they want to spend Spring Break with Bud and his pals. The girls say that in order to cheat on their boyfriends with Bud and his pals they need the tickets and reservation in order to "send away the boyfriends" and the con succeeds. Meanwhile, Al and Griff sell a lot of shoes for girls leaving for Spring Break and wish they also could go, leaving them in a cold and powerless shoe store during a city-wide blackout resulting from a blizzard. Jefferson arrives and lets it slip that he's going to Fort Lauderdale to act as a judge in a beauty contest, behind Marcy's back, of course. Al and Griff then realize they can spend the money to go to Fort Lauderdale. Marcy arrives at the Bundys to find the boys still waiting for the girls to arrive. Together, they witness the girls, as well as Al, Griff, and Jefferson on TV at Fort Lauderdale. Marcy and the boys decide to go after them to get revenge.

Al, Jefferson, and Griff are having the time of their lives at Fort Lauderdale; Al even finds a new way to earn money by collecting empty cans. The girls are prepping Kelly for the beauty competition. Meanwhile, Marcy and the boys experience some car problems on the way from Chicago to Fort Lauderdale and have to bow to the demands of a purvey Tennessee car mechanic in order to get new wheels. The girls bump into Al and his pals at their hotel suite during a party. Al doesn't want Kelly to take part in some sleazy contest...that is until he learns that the prize is $100,000.
