Sonny Munroe is starting to adjust to her new life in Hollywood, but when her best friend from back home reminds her that she’s missing the prom, Sonny is totally bummed. Then Sonny has an idea:  create a prom scene on the set of So Random! The cast thinks it’s an awesome plan—even Sonny’s rival, Tawni Hart, who agrees as long as she gets to be the prom queen. But when the producer of the show vetoes Sonny’s suggestion, can she figure out a way to make her prom dreams come true? Plus, Sonny is disappointed that she never gets any fan mail and writes a letter to herself—with disastrous results!
