Just as Zack and Kelly are getting pretty close, Kelly is accepted to the Semester on the Sea program, which involves a three-month cruise. Zack doesn't want Kelly to go, but she feels it's an opportunity she can't pass up. Zack tries to get accepted into the program as well, but none of his schemes work. He tries to get Screech to quit the program by scaring him, but that backfires. Zack has a dream that Kelly is with another guy on the ship. When he wakes up, he goes into Kelly's room, wakes her up, and asks her to marry him. Kelly says she has to think about it--and she's still going on the cruise.

Zack wants to organize a rave to raise money so the gang can go to Cancun, especially so Kelly will get over her break-up with Lasky. The original location of the rave is burned down so they move it on campus, at the Kreinberg Hall. They are caught by the Dean, but Professor Lasky covers for them. Meanwhile, Screech tries to fit in with the cool group by getting them nitrous oxide from his chemistry lab. Instead, he accidentally steals Helium.
