Fourteen-year-old twins Mia (Brisa Lalich) and Mackie Castillo (Laura Krystine, Instructions Not Included) have been dancing since they were toddlers. They support each other's passion through competitions and rehearsals, even though they prefer different styles: Mia loves tap and Mackie loves jazz. When their favorite pop star launches an online contest to find the most unique dance group, the twins each form their own team to compete for the chance to dance in the video. With the help of their friends Pauly and Doug (Trevor Larcom, Fuller House) and family, they campaign for the most votes on social media. Meanwhile, their arch-rival and neighbor Avery (Jayden Bartels, Criminal Minds: Beyond Borders), uses her charm and resources to tear sister against sister and gain the upper hand in the competition.
