She finds her house lights turned on when she returns from work, her personal effects in disarray, and someone has written "You will die" on her mirror with a lipstick.

Ashley is committed to an insane asylum and in the course of therapy is introduced to her two "alters" and relives the horrific events that shattered her mind.

It is revealed that her father, Dr. Steven, was the one who sexually abused her, causing her to develop Dissociative Identity Disorder resulting in the creation of the alter Toni, and becomes a thing of her mother's detest.

The first alter represents her struggle and fear as a helpless child without sexual maturity, and (Toni) develops into a protective one and becomes murderous when encountered with similar conditions.

While the second alter (Alette) represents her feeling of shame and pain of being breached, thus developing into a source of console exhibiting warmth and motherly love who has good rapport with Ashley.

However, Toni is enraged when she learns that the woman her father is about to marry has a three-year-old daughter and is afraid that the girl would suffer the same fate she had.

This softer side of Toni is only a front to show Dr. Gilbert she has finally accepted everything so she and Alette can get out of the asylum to kill her father, who is staying in The Hamptons for Christmas.

And I promise you that one day I'll get us out of here.In the end, Ashley is shown to be traveling on a train to The Hamptons, where her father is staying, when Toni suddenly shows up to kill him.
