Saeko, a woman with a mysterious past, is hit with a rock and brutally raped by a man wearing a dark mask and black gloves. Her life is spared, but soon brutal murders befall the residents of the Kibougahara Apartment building. The victims are beaten, killed, and their genitals are set on fire. Saeko has her suspicions about the killer's identity, but will she live long enough to unmask the pyromaniac? Sex, horror and nudity! Three great things that go great together! The Nikkatsu oddity, ZOOM IN: SEX APARTMENTS combines genres to bring you a one-of-a-kind film about a sadistic killer who literally lights up the loins of his victims! The elaborately-orchestrated rapes and murders committed by a faceless, leather-gloved psychotic (and set to a booming bass-heavy soundtrack) are an unmistakably deliberate homage to the Giallo films of Italian master director, Dario Argento.
