It introduces the six main characters of the series which are Sonny Munroe (Demi Lovato), Tawni Hart (Tiffany Thornton), Chad Dylan Cooper (Sterling Knight), Nico Harris (Brandon Mychal Smith), Grady Mitchell (Doug Brochu), and Zora Lancaster (Allisyn Ashley Arm).

Recurring cast members and guest stars this season include Michael Kostroff, Nancy McKeon, Vicki Lewis, Kelly Blatz, Selena Gomez, Eden Sher, G. Hannelius, Daniel Roebuck, Steve Hytner, Robert Adamson, Christina Moore and Jeff Dunham.

The opening sequence (which slides in from the top of the screen at the end of the teaser scene) begins with a shot of a ringing telephone, which Sonny picks up.

After a funny video she posted online goes viral, Wisconsin teenager Allison "Sonny" Munroe is offered a role as the newest cast member for her favorite TV show, a sketch comedy called So Random!

Her first day on set, Sonny meets her fellow castmates - eccentric middle schooler Zora Lancaster; dim-witted, fun-loving best friend duo Nico Harris and Grady Mitchell; and high-strung, conceited diva Tawni Hart.

Sonny decides to hold a peace picnic to dissolve the rivalry, but after this backfires, she challenges Mackenzie Falls to a Musical chairs competition, in which the losing show will have to say something nice about the winner.

Chad ends up losing after Sonny fakes an injury, leading to him then complimenting her acting skills and inviting her to join Mackenzie Falls (which she declines).

Sonny gives a studio tour to an underprivileged girl named Dakota (G. Hannelius) who claims to be from the Children Having A Dream Foundation.

It is eventually revealed that Dakota is a stuck-up, stubborn brat who is actually the daughter of the studio's owner, Mr. Condor, and faked the Children Having A Dream foundation so she could meet Chad, as she is not allowed to watch Mackenzie Falls due to being younger than the show's target age demographic.

Sonny eventually caves and brings Dakota to "The Basement," a fake nightclub created by Tawni, so she can meet Chad.

Chad instructs Nico to scare the two in a Bigfoot costume (inspired by a Mackenzie Falls episode) but the incident just brings Marshall and Ms. Bitterman closer.

Chad is making an autobiographical movie about his life and hires actress Selena Gomez to play the role of Sonny.

This culminates in Gomez storming off set and quitting the movie after she gets fed up with Sonny and Chad's constant arguing, though not before she manages to get the two to allude to having crushes on one another.

Meanwhile, Nico and Grady meet a pair of actors who look identical to them, but somehow have much better luck with girls, and enlist their doppelgängers' help in picking up women.
