Stars Dance Studio's best dancers Sammy and Jessi are paired with Hannah in a trio, but when rehearsals run long, dance mom Abby breaks the rules and pulls Sammy from practice early. Dance mom Susan is upset and after several heated matches pushes Abby to her boiling point.

With no sign of Abby or Sammy, the moms assume they have quit the Stars dance team for good. But when the pair surprises the group with their return, the other dance moms go on the offensive blaming Abby and Sammy for their lack of team spirit.

Stars Dance Studio's dance mom Leonora and her popular daughter Mia join the competition team ruffling the feathers of all the other moms. And when Mia is given extra attention by the instructors, the moms go off the deep end.
