The gang takes a vacation to Hawaii for some R & R. Meanwhile, the Principals of L.A. are taking a tour of Hawaii and guess who is the tour-leader? Mr. Belding! While in the Hawaii airport, Lisa bets the newly dating Slater and Jessie $50 each that they can't get along without fighting for 2 weeks. Also in the airport, Zack meets a Hawaiian native, Andrea Larson, and he believes it is love at first sight. But her boyfriend, Derek Worthington, picks her up and Zack doesn't think he will see her again. The gang stays at the hotel, "The Hideaway", which Kelly's Granfather, Harry Bannister, owns. The Principals stay at The Royal Pacific.
Harry tells the gang that he is probably going to sell to The Royal Pacific for their expansion because they have all but put him out of business. The gang decides to help him by becoming his volunteer staff. They go to the Royal Pacific and make all the Principals mad by posing as Royal staff and giving terrible service. So Belding decides to move the tour to the Hideaway. While they are at the Royal Pacific, Zack sees Andrea again. She is an Activities Director for the hotel, and her boyfriend, Derek, is the son of the owner, Charles Worthington. Harry's lawyer, Brian Hanson, hits on Kelly and they start to get close. He convinces Kelly that selling the Hideaway is in her grandfather's best interest.
Meanwhile, some members of the Pupuku tribe kidnap Screech and Lisa. When they get to their village, they tell Screech that he is their new Chief. Apparently, Chief Monaleo told these natives that his descendant would save them, and the statue of Chief Monaleo looks like Screech. The tribe is afraid that the hotel is going to steal their land and build on it, but they have no deed to prove they own the land.
Zack and Andrea spend a lot of time together and he is falling for her. She then introduces him to her 6 year old daughter, Jennifer. Zack gets along great with Jennifer and he and Andrea get closer.
Kelly (on Brian's advice) convinces her Grandpa to sell. But then Lisa overhears Brian talking to Charles Worthington about a loan extension. Brian is out to hurt Harry by making him lose everything. The gang comes up with a plan. Belding poses as a professor of Polynesian Culture and Zack makes a fake deed to the land for the Pupukus. Brian takes it to Worthington and he burns it, but not before Screech sets up a hidden video in the office.
Zack shows the tape to Worthington and he backs down from buying the Hideaway land and taking the Pupuku's land. Andrea quits her job after she hears what jerks Derek and his father are. Kelly punches Brian in the face.
It's time for the gang to go. Harry offers Andrea a job as his new manager. The Pupukus become his staff. Zack is heartbroken about leaving Andrea and Jennifer and he tells her he will move to Hawaii. She tells him no, that everything will work out.And of course, Jessie and Slater lost the bet to Lisa and she becomes $100 richer! The gang goes back to California.
