Abby Lee Miller is back with Pittsburgh's world-class students, their mothers, and all their baggage in this DANCE MOMS Collectors Gift Set of Seasons 3 and 4. Get ready for more drama and dancing as everyone gets into their routines. You'll meet several new dancers who join the others in vying to be Abby's new favourite and bring home National Dance titles. In Season 4, Abby takes to the road with a new national scouting tour to find the country's most elite young dancers. With the threat of new dancers coming into the 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. But despite even more mama drama, what Abby Lee Miller says, goes. And when she says, Everyone is replaceable, she means it!
