Is there something sinister about Madame Leona's dance troupe?

When Melanie Clark's best friend, Pauline, dies in a car crash, the police write it off as an accident, but Melanie isn't so sure. Pauline was acting strange in the weeks before she died, and Melanie believes Pauline's dance teacher, Madame Leona, may have had something to do with that.

In order to learn more about the mysterious hold Madame Leona has on her students, Melanie joins the teacher's prestigious dance group. She's determined to find out the truth behind Pauline's death—no matter what it takes.

But as she becomes more involved, Melanie starts to forget why she joined in the first place, falling deeper and deeper under Madame Leona's spell. Can Melanie escape the woman's magnetic grip, or has she lost herself forever?
