Leonard Shelby, an employee of an insurance company, was concerned with the investigation of claims until, one night, his wife was raped and murdered in their apartment. Shelby himself was knocked unconscious after killing one of the murderers. The other murderer was able to escape without being identified. The police then assumed that there had only been one murderer who, in turn, had also been killed. Having been hit on the head, Leonard suffers from partial amnesia, from the loss of short-term memory. Despite this, he searches for his wife's escaped murderer (Memento; By Christopher Nolan). What's your idea about short memory loss? Your  memory up to the moment of crash is remained intact but you can't remember the name or face of persons with whom you  speak one hour ago. By the Way, do you think that leonard can find the murderer?
