Jane Morton, a psychiatrist from Dublin in deep mourning
following the accidental death of her husband and son, is
assigned to work on the case of Dorothy Mills, a teenaged
girl in a small village who tried to strangle a baby.
After miraculously surviving a car accident, Jane
discovers a village darkened by strange events and meets
a very nervous Dorothy, who swears she never touched the
baby. After analyzing the teenager, Jane makes a
diagnosis of multiple personality disorder until the day
that Dorothy speaks with the voice of David, Jane's dead
son.
