When Carly takes the blame for one of Sam's pranks, Miss Briggs makes them run talent show tryouts. Before too long, they decide to host their own online web show.

Carly and Sam compete against Freddie and Spencer to see who can come up with the best plan to get more viewers for the iCarly webcast.

iCarly asks their fans to send in videos of themselves doing their coolest dances. When over three thousand dance clips come in, Carly, Sam, and Freddie find themselves trying to stay up all night to watch the videos.

Carly is excited that her crush, Jake Krandle, is going to play guitar. However, Jake turns out to be a terrible singer, so Carly turns to Freddie to save the day.

Carly and Spencer's granddad makes a surprise visit. He's very concerned that Spencer is too irresponsible and wacky to be Carly's guardian. It's up to Carly and her friends to prove to her granddad that Spencer is capable.

The gang want their web show to be reviewed by Nevelocity, a popular website, but Carly discovers that Nevel's actually an annoying 11-year-old boy who's far more interested in dating her.
