Right after World War II Jimmy Picard (Benicio Del Toro), a Blackfoot Indian who fought in France, is admitted to a military hospital in Topeka, Kansas. The institution is specialized in brain diseases and Jimmy Picard suffers from many problems : dizziness, temporary blindness, and hearing loss (a case of post-traumatic stress disorder?). In the absence of physiological causes, he’s given a diagnosis of schizophrenia.
