I KNOW WHO KILLED ME begins as Aubrey Fleming (Lindsay Lohan), a high school student with serious goals as a writer, describes a fictional character she's made up, a stripper named Dakota Moss. Though Aubrey is kidnapped by a serial killer preying on local girls, she manages to escape the fate of all his other victims and survives. When she is found two weeks later after enduring horrible torture, she claims to be Dakota. The horror that Aubrey endured under the hands of the killer is only the beginning in this thriller, as Aubrey/Dakota questions her own sanity and sense of reality.
