Zoom Up: Rape Site

Zoom Up Bōkō Gemba (ズームアップ　暴行現場) is a 1979 Japanese film in Nikkatsu's Roman porno series, directed by Kōyū Ohara. This film is the first in Nikkatsu's "Zoom Up" series and its success led to six more sequels in the same motif. It represented a return to the ultra-violent, misogynistic "Violent Pink" style which Nikkatsu had curtailed after the 1977 Rape! 13th Hour.
