The Bayside gang (Zack, Screech, Jessie, Lisa, Slater, and Kelly) decide to go on a vaction to Hawaii to relax. Incidentally Mr Belding is also going on a trip to the same location as the gang as part of a tour with a group of principals. Zack meets a beautiful Hawian native Andrea and pursues her to the fullest of his abilities. Even the fact that she has a son it seems does not deter Zack.
Kelly falls for someone on the island as well. Kelly's grandfather owns one of the hotels on the island and is considering selling it to a developer. At first everyone thinks this is a great idea until some of the developers deceitful methods are discovered. The developer used a guy to convince Kelly to talk her dad into selling. This is found out only after the documents to sell have been signed. A tribe of Native Hawaiians find Screech unique, and kidnap him and offer him the chance to be chief of their tribe.
Zack has a fake deed to the hotel Kelly's grandfather owns made up in the hopes that it can be used to cause the developers to back out of the deal to buy the hotel. Zack has the deed made up so it appears the tribe that Screech "leads" is the owner. The developer backs out and the gang ultimately packs up and prepares to return to home. Zack says his goodbyes to Andrea the native that he would have stayed for if she wished. Kelly dumps the guy that she was with. And during the whole adventure, Lisa made a small bet of $50 with Jessie and Slater that they couldn't go without fighting for the two weeks of the trip. She collects her prize from each of them.
This made for TV movie marks the end of the magical group from Bayside that changed lives and made life fun for millions at home. The movie featured Mike Rogers, and Alex Tabor from the College years as well as the original gang from Bayside (Zack, Kelly, Lisa, Screech, Jessie, Slater, and Mr Belding). The cast reunited even though the gang was not together during the College Years episode.
The movie begins with Zack, Screech, and Slater playing paintball in the woods. Zack and Slater are surrounded and about to be shot, then a schme is born. Slater and Zack pretend to be fighting. Since paintball is just a game the other team members don't know what to make of this and hence shoot no one in the confusion. Screech emerges and shoots all the other team members, and Zack and company win.
The gang prepares to travel home, but while driving through they happen to come by Bayside High. The outside of the school is shown for the first time ever. The gang thinks back to the good times they had and then proceed to their respective homes. Zack tells his parents about his plans to marry Kelly, his father is furious. Zack then sneaks out with the guys and plans to travel to Las Vegas to marry Kelly. The guys make a bet with the girls to see who can make it to Vegas first.
Zack worries that the money he has will not be enough to get them to Vegas and pay for the marriage. Zack and the boys get arrested and spend time in jail and find themselves short on cash. They take up jobs as male escorts. Zack has to be an escort at the same time he has a planned date with Kelly and trouble ensues. In the end Zack's parents come around and visit the grand wedding of Kelly and Zack
