Miley Stewart and her best friend Lilly Truscott arrive at a concert and race through the crabdoor just in time for Miley to perform as her secret alter ego: pop superstar singer Hannah Montana. After filming a music video for her song “The Best of Both Worlds”, Miley – as Hannah – is confronted by Oswald Granger, an unscrupulous tabloid reporter. Hannah’s manager Vita sends Oswald away, but he manages to record her alluding to Hannah’s “secret”, which he becomes determined to uncover.
While shopping as Hannah, Miley fights with Tyra Banks over a pair of shoes, making her late for Lilly’s birthday party. Oswald records the incident and follows her to the party, forcing Miley to attend as Hannah in order to prevent him from learning her secret. Hannah’s presence steals the entire party’s attention, as does her performance of “Let’s Get Crazy”. Lilly leaves dejected and is stopped and questioned by Oswald, to whom she reveals that Hannah is from Crowley Corners, Tennessee.
Already upset with Miley for prioritizing her celebrity life over her family and friends, her father Robby is infuriated when her fight with Tyra makes headlines. He allows Vita to book a private jet for Miley to attend an awards show as Hannah, but instead flies her to Crowley Corners to spend two weeks there for her grandmother Ruby’s birthday. Miley is eager to return to being Hannah, but Ruby chastises her for neglecting to spend time with her family.
