A hair-raising psychological documentary by Jan Soldat portrays three men whose concealed fantasies will evoke disgust and shock in some viewers. The protagonists wish to be slaughtered, dismembered, and eaten. A more insightful audience member may find references to famous cannibalistic films (“Cannibal Holocaust,” “The Silence of the Lambs,” “Grimm Love”).
