The story focuses on three non-linear narratives, two of which are centred on real people. Thomas Harvey is the pathologist who conducted the autopsy on Albert Einstein and became obsessed with what could be revealed from research into his brain. The second story based on fact is of Henry Molaison, a 27 year old-man who - after an operation to cure his epilepsy - lost his short term memory which left him unable to remember the detail of conversations he had been having seconds earlier. The third story revolves around a fictitious neuropsychologist, Martha, who has a somewhat nihilistic view on identity and memories.
