When Carly Shay and her best friend Sam Puckett improvise comedy at a school talent show audition, tech-savvy Freddie Benson records it and posts it online without informing them. After seeing the girls' strong chemistry and banter, the online audience clamors for more, and thus they decide to create iCarly. The trio find their normal adolescent lives thrown for a loop when they discover that they have become online sensations as their show – which features talent contests, recipes, problem-solving, and random dancing – garners international accolades. Carly lives in Seattle with her adult brother and guardian Spencer and produces the show in a makeshift third-floor studio loft in their apartment. Their father, Steven Shay, is a United States Air Force officer stationed on a submarine and is often mentioned, but is only seen during the series' finale episode, "iGoodbye".

"iGo One Direction"

After returning from vacation, Carly falls ill with "Jungle Worms", but feels better after two days, although she is still contagious. Later, Freddie tells Sam, Carly, and Gibby that he has received an e-mail from the manager of boyband One Direction (whom Gibby appears to be a massive fan of), saying that they are in the Seattle area and would like to perform a song on iCarly. When they arrive, One Direction performs "What Makes You Beautiful" in the iCarly studio. (Afterwards, Sam takes a liking to Zayn Malik while Gibby tells Niall Horan and Louis Tomlinson that he gives good foot massages). After Harry Styles drinks from Carly's water bottle, he gets Jungle Worms from Carly, and then she takes care of Harry and he is still in bed after a week, much longer than Carly was sick for, making Sam believe that Harry is not actually sick anymore and just wants the attention. Liam Payne announces that the boys will have to cancel their shows in San Francisco if Harry is not better soon, so Liam, Zayn, Niall, and Louis discuss with Carly, Sam, and Freddie what to do to try to get Harry out of bed. Freddie says that Harry might feel better if he thought that he was being kicked out of One Direction and being replaced by Gibby, and when he sees Gibby performing with Liam, Niall, Louis, and Zayn, Harry is shocked by how bad Gibby is at singing and dancing and says that he is feeling better, meaning that he was faking. The episode ends with One Direction performing "What Makes You Beautiful" on iCarly. After the song, Sam grabs Zayn by the neck and drags him into the elevator.
