Bilanggo sa dilim (1986)

A young photographer, who calls himself Lito (Joel Torre), becomes obsessed with Margie (Rio Locsin), a pretty but desperate student who moonlights as a prostitute. Luring Margie to his far-off beach house, Lito turns her into a virtual prisoner under his total control. But Margie's easy submission to his demands turns him off and his obsession turns to Marissa (Cherie Gil), a lovely and smart fashion designer/model whom he idealizes as the perfect captive. He abducts Marissa and brings her to his beach house. Introducing himself as Eddie this time, he soon realizes that Marissa is far from the girl he fantasized about. "Bilanggo sa Dilim" was the first Filipino feature-length film shot entirely on analog video. It premiered as the opening film of the First Independent Film and Video Festival at the Wave Cinema in August 1986.
