Issei Sagawa sits for a filmed interview and describes, in his own words, killing and eating a fellow student in Paris in 1981. The film traces how Sagawa, a Japanese literature student, murdered Dutch classmate Renée Hartevelt and spent three days consuming parts of her body before being caught. French authorities declared him legally insane and unfit for trial, and after a stint in a French psychiatric hospital he was deported to Japan, where doctors found him sane and released him outright, since no formal conviction existed to enforce. The documentary follows what happened next: Sagawa turned his notoriety into a career, writing books, appearing on television, and drawing manga about his crime, becoming a minor celebrity in Japan while remaining free. Interview footage, archival news clips, and Sagawa's own unsettling calm carry the film, which offers no narrator to soften or explain his answers, leaving his account of the killing and its aftermath to speak for itself.
