Tracy Turnblad, a big girl with big hair and an even bigger heart, has only one passion - dancing. Her dream is to appear on "The Corny Collins Show," Baltimore's hippest dance party on TV. Tracy (Nikki Blonsky) seems a natural fit for the show except for one not-so-little problem - she doesn't fit. Her plus-sized figure has always set her apart from the in-crowd, which she is reminded of by her loving but overly protective plus-sized mother, Edna (John Travolta). That doesn't stop Tracy because if there is one thing that this big girl knows, it's that she was born to boogie.
Viola Johnson (Amanda Bynes) had her own good reasons for disguising herself as her twin brother Sebastian (James Kirk) and enrolling in his place at his new boarding school, Illyria Prep.

What she didn't count on was falling in love with her hot roommate, Duke (Channing Tatum), who in turn only has eyes for the beautiful Olivia (Laura Ramsey).
