This documentary examines the remarkable case of Issei Sagawa, who walked free from prison despite having killed and eaten a young woman in the early 1980s. The film interviews Sagawa alongside police officers, journalists and psychiatrists to piece together the shocking story of his crime and his subsequent rise to become a minor celebrity in Japan. In June 1981, police in Paris were alerted to the discovery of two suitcases containing human remains left by a small Asian man in the Bois de Boulogne park.
