I Know Who Killed Me (2007)

Synopsis
Lindsay Lohan stars in the mind-bending psychological thriller I Know Who Killed Me. She plays Aubrey Fleming, an unfortunate young woman whose life -- and body -- are irreparably damaged following an abduction by a heinous serial killer. Though Aubrey pulls off a miraculous escape from the clutches of the madman, she does so with deep-seated psychological scars, plus the loss of a hand, a leg, and untold amounts of blood. While Aubrey's parents view her return as a veritable answer to their prayers, they must soon confront an outrageous and seemingly inexplicable twist: the girl who returned claims another identity -- that of a young woman named Dakota. She also exhibits a wholly different personality and mannerisms than Aubrey did, and -- frighteningly -- insists that Aubrey is still very much alive, in the throes of the maniac's grip, and only inches away from death. ~ Nathan Southern, All Movie Guide
