Abby Lee Miller and all of your favourites return to the stage in this second collection of DANCE MOMS® Season 4. Abby’s new completion team is taking shape and as more auditions occur for Abby Lee Dance Company, the moms will stop at nothing to ensure their girls have a place to shine on stage – even if it means going up against Abby. Maddie and Mackenzie go head-to-head for the first time ever and the impending arrival of a brand new dance group looms over Abby’s original line-up.
