Allison "Sonny" Munroe moves from the Midwest to Los Angeles to join the cast of "So Random!," the most popular sketch comedy show for kids and tweens. Her fellow young actors are Tawni, who is the resident teen queen, Nico, who is very cool, Grady, who is a friendly funnyman, and Zora, who is different. Now, Sonny has to find a way to balance these new friendships with the very different way her family lives in Hollywood. Sonny also has to deal with Chad Dylan Cooper, the star of the rival show "MacKenzie Falls," who is a heartthrob and says that he thinks his dramatic work is better than her comedy work.
