Joji Obara, born in Osaka in 1952, is a convicted rapist linked to the deaths of two women he is accused of drugging and assaulting: British hostess Lucie Blackman, who vanished in the summer of 2000, and Australian Carita Ridgway, who died in 1992. The film lays out the case built against him, including the six other rapes he was convicted of, and the pattern investigators traced through his private videotapes and property records once Blackman's disappearance forced police to look closely at his history. It follows the two-family thread running through the case, one seeking a body, the other seeking a conviction for a death that predated it by years, and shows how a single suspect connected both. With sources limited mainly to the case's bare facts, the film stays close to the charges, the victims, and the timeline rather than speculating beyond what the courts established.
