When Payton and Emma take on a trio of triplets at the Twin Festival, it's double--make that triple--the twin-switch fun! Emma and Payton are home from Hollywood, but the drama continues: Not only is the Homecoming Dance coming up fast, but there's someone new in school! Three someones, actually: triplets. Oliver, Dexter, and Asher look exactly the same, dress exactly the same, and--worse--have exactly the same superior attitude. When the triplets mention they're participating in a regional Twins & SuperTwins Festival that has a Tweens Division and twin-related contests, Payton and Emma are instantly interested. Emma's been suffering from competition withdrawal ever since Jazmine James managed to get her disqualified from the upcoming science fair, so she's got her game face on. And once Payton convinces Mrs. Burkle that the festival is perfect for a VOGScast field trip, the whole gang takes a road trip and the games really get going. But attempts to take down the triplets threaten to land everyone in hot water. Can Emma and Payton switch their way out of trouble, or are they stuck in a multiples mess?
