When Carly Shay (Miranda Cosgrove) comes back to Seattle, she thinks that her friends (Freddie, Sam and Gibby) won't be her best friends anymore. So, Carly started to spy on his friends before doing anything else. Carly found out that Sam has moved out and is living in Los Angeles with Cat (Arianna Grande). Carly knocks on Freddie's door and tells Freddie (Nathan Kress) that both of them should get Sam (Jennette McCurdy) to Seattle to start up iCarly again.
When they arrived at Los Angeles, they convinced Sam to start up iCarly again and have it just the way they had before Carly moved to Italy. Sam and Cat said farewell to each other. Freddie, Sam and Carly boarded a plane and flew back to Seattle.
