The season features Carly Shay (Miranda Cosgrove), Sam Puckett (Jennette McCurdy) and Freddie Benson (Nathan Kress) as they continue their own Web Show called iCarly.
This season had the specials "iThink They Kissed", "iMove Out", "iQuit iCarly" "iSaved Your Life", "iSpace Out", "iBloop" "iWon't Cancel the Show" and "iPsycho".
In the season opener, Sam, intoxicated and giggly from nitrous oxide, spills the beans to Carly about her and Freddie's first kiss, which she cannot remember soon afterwards.
Three months later, Freddie pushes Carly out of the way of an oncoming taco truck on the road, saving her life and getting himself injured in the process.
Eventually, Spencer's date appears in the studio and runs out after being humiliated on the web.
