Tracy Turnblad(Nikki Blonsky), an overweight teenager with all the right moves, is obsessed with the Corny Collins (James Marsden) Show. Every day after school, she and her best friend Penny (Amanda Bynes) run home to watch the show and drool over the hot Link Larkin (Zac Efron), much to Tracy's mother Edna (John Travolta) 's dismay. After one of the stars of the show leaves, Corny Collins holds auditions to see who will be the next person on the Corny Collins show. With all of the help of her friend SeaweedElijah Kelley, Tracy makes it on the show, angering the evil dance queen Amber Von Tussle (Brittany Snow) and her mother Velma (Michelle Pfeiffer) . Tracy then decides that it's not fair that the black kids can only dance on the Corny Collins Show once a month, and with the help of Seaweed, Link, Penny, Motormouth Maybelle, her father and Edna, she's going to integrate the show.....without denting her 'do!
