I Know Who Killed Me 2007

In New Salem, the upper-class high-school student and aspiring writer Aubrey Fleming has just quit the piano classes to dedicate to write. When the mutilated body of her missing schoolmate Jennifer Toland is found, the locals grieve the student while the police chase the killer. After a football game, Aubrey is kidnapped and then she is mutilated by the serial-killer. A couple of weeks later, Aubrey is found unconscious in a lonely road and brought to the hospital with severed hand and foot in the same modus-operandi Jennifer was mutilated. When she awakes, she tells that she is the stripper Dakota Moss and her junky mother had an overdose and died. When the FBI finds that Dakota is one character of Aubrey's stories, they conclude the girl needs psychiatric treatment and protection. But Dakota insists she is not Aubrey.
