Current Season: The Understudy

How far would you go to protect your daughter? Carolyn, Bronnie, Elise, and Kendall are bound together by one thing—their four daughters are best friends at the highly competitive Orla Flynn Academy for the Performing Arts. Last year the foursome exploded because of brutal bullying between the girls, but they've since forgiven each other. The mothers, however, haven’t been able to move on. When new threats surface and "accidents" begin to happen—just as a mysterious new girl enters the scene—the mothers take matters into their own hands. But they will have to risk their own secrets being exposed if they stand a chance at uncovering the truth.
