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 English-Irish boyband One Direction (whom Gibby appears to be a massive fan of), saying that they are in the Seattle area and would like to preform a song on iCarly. When they arrive, they perform "What Makes You Beautiful" in the studio and 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 her germs and catches Jungle Worms. Carly 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 any more and just wants to be near Carly. After Liam Payne announces that the boys will have to cancel their shows in San Francisco if Harry is not better soon, Liam, Zayn, Niall and Louis discuss with Carly, Sam and Freddie what to do to try and get Harry out of bed. Freddie says that Harry might feel better if he thought that he was being replaced by Gibby. After Harry sees Gibby performing with the other four boys, he 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 drags Zayn into the elevator.
