Maki is taken by a man with obsessive delusions and subjected to training according to his self-written future diary. As the process unfolds, her body gradually begins to ache with desire, consumed by the man's fantasies. Exhibitionist acts take place in a video rental shop, and she is made to wear a collar, treated like a pet. Explicit scenes unfold in broad daylight—urination, vibrator use, and outdoor sex—so lewd that viewers cannot help but feel disturbed. The man's fantasies escalate uncontrollably, driving Maki's body into madness, until she completely loses her own will.
