Lizzie and Miranda are excited about the news that singer Aaron Carter is coming to their town to do a video shoot. They enlist Gordo to help them figure out where the shoot will take place so they can crash the set and meet Aaron. Matt horns his way into the group also. When they arrive at the site Matt is mistaken for Aaron's stand-in and let on the set, but the other three are not. They try several ways to sneak in but are always chased off by a security guard. In all the confusion Mr. and Mrs. McGuire somehow manage to get detained by security. Aaron's manager catches the trio and Lizzie convinces her to at least let one of them meet Aaron. She agrees, and Lizzie tells Miranda that she can be the one. Lizzie goes back to get a tape recorder she left behind and runs in to Aaron, who gives her a kiss. The kids all get to be extras in the video.

Lizzie starts feeling inferior when she realizes a lot of the other kids around her have special talents and skills that they've developed, including Gordo with his film making and Miranda with her violin.

Lizzie fervently hopes to win the grand prize in the Christmas parade with her idea for a "Rock & Roll Christmas" float. The rest of the McGuire family are there, and they are charmed by an eccentric old man in an elf suit who calls himself Nobby Frostybump and seems to really believe he's one of Santa's elves!
