Maths whiz Emily Martin has won a place in a video game competition - on a summer cruise! And her best friends Bella, Grace and Chloe are with her all the way.
While onboard, the girls set themselves a few anti-princess missions: win the regatta, rescue the endangered turtle, show the gift shop manager that dolls can be more than be pretty, and prove to the gamers that girls can compete - and win!
Can the anti-princesses work together to complete their missions, and maybe pick up some new members along the way?
