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 seems a natural fit for the show except for one not-so-little problem--she doesn't fit in. Her plus-sized figure has always set her apart from the cool crowd, which she is reminded of by her loving but overly protective plus-sized mother, Edna. That doesn't stop Tracy because if there is one thing that this girl knows, it's that she was born to dance.
