A professional voyeur and an elusive serial killer both suffer from a sensory disorder that affects on in 100,000 people in director Toru Matsuura's hallucinatory thriller. Shin suffers from synesthesia, a rare sensory disorder in which one form of stimulus triggers a completely unrelated response. His constant mental state borders on insanity, and he makes his living by providing voyeuristic videos to a well-paying clientele. When Shin discovers evidence of a serial killer named Picasso who also suffers from synesthesia, his already-warped world is thrown into total chaos. Picasso is leaving hidden messages in his victims' blood, and only Shin can decode those carefully hidden clues. Now, as Picasso entrances his victims with a hypnotic video game, Shin puts his own sanity at risk in order to stop the madman from striking again.
