The teenagers of Disney's most infamous villains return to the Isle of the Lost to recruit a new batch of villainous offspring to join them at Auradon Prep.

Mal struggles with her new celebrity life as the girlfriend of King Ben, putting a spell on her hair making it blonde, and maintaining a princess-like personality that she is uncomfortable with. She admits her issues to her friends Evie, Carlos, and Jay, but they are content with their new lives in Auradon and do not wish to return to the Isle of the Lost. Evie scolds Mal for relying on her mother's spell book to solve her issues. Carlos, wishing to ask Jane to the upcoming Cotillion dance, turns to Mal for help to be honest with her. Mal gives him a sweet that will make him speak the truth, but his dog Dude eats it, magically speaking the truth in English and very frankly as a result.
