Featuring the voices of Kelly Sheridan, Jennifer Waris, Ashleigh Ball, Tiffany Giardina, Ellie King and Peter Kelamis, the plot follows two teenage girls, Keira, a world-famous popstar, and Tori, princess of Meribella (both portrayed by Barbie) who meet and discover they both have the magic to swap places.

Famous popstar Keira is giving a series of concerts to commemorate the event; behind the scenes, she is overwhelmed, between being unable to write new songs and dealing with her overeager manager, Seymour Crider.

Meanwhile, Tori is having fun rehearsing as Keira, but when freely exploring the kingdom, she discovers how badly the ongoing drought has affected the people.

The girls decide to extend the switch for another day and make Keira's final concert a free one so more people can afford to attend.

The following night, when the girls are supposed to switch back, Keira is locked in the Princess's bedroom by the Duchess because of a commemorative speech Tori has been procrastinating.

"Here I Am (Keira Version)" is a song recorded by American singer Tiffany Giardina for the 2012 CGI-animated movie Barbie: The Princess and The Popstar.
