"Hannah Montana" aka Miley Stewart, is the hippest 14-year-old transfer from Tennessee to come to Malibu, bringing along her brother, Jackson, and father, Robby. With her best friends Lilly and Oliver, they weave and navigate the tangled web of school life - from getting good grades, to impressing her crush, to being accepted socially!

As awkward as Miley sometimes feels as a teenager, she undergoes a transformation when performing on stage. Miley's classmates are totally out of "the know" when it comes to her double life as pop singer, Hannah Montana. She travels the world, entertaining fans with the music written by her manager who's also her dad.

Miley lives a life that any kid dreams to have, but while the glamour and fame do have their perks (limousines, cool clothes and hanging out with celebrities) Miley just wants to be treated like any other teenager and experience the typical life led by her friends!
