Dorothy Mills (2008)

Jenn Murray is Dorothy Mills, a teenager in a small Irish village who tried to kill a baby, and Carice van Houten is Jane Van Dopp, the psychiatrist assigned to evaluate her in the mystery thriller Dorothy Mills (2008). After examining the girl, Jane diagnoses her with multiple personality disorder but is thrown for a loop when her patient begins speaking in the voice of Jane’s dead son. In one scene, one or another of Dorothy’s personalities decides to flash her rack at the driver of the car she’s riding in. That’s the personality she should stick with.
