Juliette and Justine prep for their first ever science fair projects, when a gender-biased comment leaves them angry. But when Justine is accidentally entered as "Justin" in the competition, she decides to go along with it in the ultimate social experiment to see if boys are favored over girls when it comes to science.
We meet Juliette and her soulsie squad — Justine, Ella, and Izzy, who are the creative minds behind their website, “Miss O & Friends - created by girls, for girls.” But problems arise when Juliette’s little sister, Olivia, gets into an argument with Harlie, her BFF, and Juliette and the soulsie squad encourage the girls to dance-it-off.
