Hairspray (1988)

When Tracy Turnblad (Ricki Lake), an overweight teen, auditions for a spot on a popular teen dance show, she beats out the spiteful Amber von Tussle (Colleen Fitzpatrick), winning over Amber's boyfriend (Michael St. Gerard) in the process. After meeting some black students at her school, Tracy begins to push for more racial integration on the dance show. This gets her into trouble on many sides, especially with Amber's pushy parents.
