Miley joins the Art Stars club for performing girls and invites JoJo to come along for a weekend kickoff event at a California national park. Art stars from across the country meet at the lake for kayaking, hiking, swimming, and of course s'mores-making. However, when the Queen Bs show up, mean girls from JoJo's dance workshop, all the girls take sides--but then Belle, the meanest mean girl, goes missing, and all the Art Stars will have to pull together to find her.
