Maria and the others are trying to win tickets to the Grungefest from the radio station, but Lindsay wins them on her first try! Tommy has told Lindsay that he wants to get back together with her, so she must choose between him and Ryan. The girls hold a slumber party to help Lindsay decide. Tommy borrows some high-tech communication equipment that Screech has bought for the school and he plans to bug Lindsay's room. Ryan has the same idea, though, and he gets R.J. to help. Eventually all the boys end up hiding in Lindsay's closet or under her bed. A few more misunderstandings occur until Lindsay finally decides to go to the show with Maria. (thetvdb.com)
