Memento (2000)

Leonard Shelby turns his anterograde amnesia into a lethal weapon of self-deception, using Polaroid snaps and ink to construct a bogus quest for vengeance. His desperate need to play the noble vigilante leaves manipulated innocents murdered and crooked cops dead in abandoned warehouses. He is the ultimate rogue investigator whose fabricated clues ensure a perpetual cycle of blood and self-inflicted misery.
