Carly is a young teenager living in Seattle. When her friend Freddie accidentally leaks a video of her and her best friend Sam onto the Internet, they decide to create an online web show.

Jake Krandle, one of the cutest boys at Ridgeway Middle School breaks up with his girlfriend, and all the girls at school want a piece of him. Carly thinks she'll get just that when she invites him on her web-show to perform some songs he wrote. But during a rehearsal, Jake is found to be a horrible singer, and Carly has to struggle to convince an already jealous Freddie to digitally enhance his voice.

Nevel Papperman is back, and instead of trashing iCarly in his articles, he has directly sabotaged the website itself. Meanwhile Spencer persuades the Plain White T's to perform on Carly's show as a favor for preventing lead singer Tom Higgenson from being hit by a falling sign at the mall. But how do they expect the band to perform on a show nobody can see?

For the science project, Carly and Sam choose to raise chicks, and they have to search the apartment frantically when they hatch sooner than anyone expected.

On the fifth anniversary of their friendship, Carly gives Sam a one-of-a-kind iCarly T-Shirt as a gift. Desperate for an attempt to return the favor, Sam tries to buy a pair of hard-to-find concert tickets for Carly's favorite band from a scalper. With no other means to purchase the tickets, she sells him the shirt and puts both Carly's show and their friendship at risk.

Carly and martial-arts champ Shelby Marx (Zoey 101's and Spectacular!'s Victoria Justice) agree to have an exhibition fight for charity after Carly jokingly challenges her to a match. Unfortunately, Carly accidentally falls on Shelby's grandmother during a press conference. Thinking Shelby wants revenge, Carly backs out of the fight, only to be ridiculed as a coward. Carly visits Shelby and apologizes, and the fight is back on. However, Nevel Papperman alters a clip of the press conference to make it look like Carly intentionally tackled Shelby's grandma to dupe Shelby into fighting Carly. Shelby, furious, attacks Carly for real during the match, Carly then holds Shelby's leg for the rest of the "fight".
