After being put on indefinite leave by his chief of police uncle, the highly intelligent and arrogant huntsman spider Inspector Sun boards a San Francisco bound seaplane. Joined by an intrepid young fan, Sun is pulled into a murder case where the turnout could affect both the insect and human worlds.

Jack—an introverted and solitary man in his thirties—pursues his passion for horror cinema with an almost fanatical zeal. His bedroom resembles a macabre mausoleum, filled with posters, film stills, video tapes, and Super 8 and 16mm films. Eventually, the movies cease to satiate his hunger for fear and morbid thrills; Jack needs to find something stronger—something real: death in the flesh, *snuff* films. His online search for snuff material—combined with his hateful relationship with his violent, alcoholic father and his obsessive, platonic love for his young neighbor—will lead Jack to the very gates of hell.
