Carly Shay (Miranda Cosgrove) lives in Seattle, Washington with her 26-year-old eccentric brother and guardian, Spencer (Jerry Trainor). Their father, U.S. Air Force Colonel Steven Shay, is temporarily stationed on a submarine. The story begins as Carly and her best friend, Sam Puckett (Jennette McCurdy), goof off at a school talent show audition. Their tech-savvy friend, Freddie Benson (Nathan Kress) films them and posts the footage online without telling the girls. It becomes a big hit, the online audience clamors for more and the kids create the iCarly webcast series. They produce the show in a makeshift third-floor studio loft in Carly’s apartment. Carly and Sam appear on-screen — acting in skits, making recipes, answering viewers questions, and dancing randomly — and Freddie is their technical producer. While dealing with typical teenage issues, the kids also become online celebrities as their show garners international attention. As the series progresses, their odd friend Gibby (Noah Munck) takes part in the fun.
