New transfers to Bayside include three students from arch-rival Valley High: R.J. "Hollywood" Collins, head cheerleader Maria Lopez and Ryan Parker, who stole Bayside's mascot the year before. The old gang greatly resents these newcomers. Ryan makes plans to date Lindsay, make Maria the head cheerleader and get R.J. to emcee the Welcome Back dance. The two groups fight so much that Mr. Belding makes them stay on separate sides of the gym at the dance and wear identifying badges. But before the night ends, the enemies all dance with each other. Also, Tommy D. is thinking of how to get back together with his old girlfriend, Lindsay.
