It's a story about a young model with daddy issues who moves into a spacious Manhattan apartment which just happens to be the gateway to hell. This discovery, as you might imagine, takes a toll on our poor heroine, but not on her wardrobe.
Despite her emotional unravelling, she wears amazing wide-legged, high-waisted jeans and floaty disco dresses right up to the point of her demise, when, after losing her boyfriend (played by Chris Sarandon) to the dark side, she sacrifices her burgeoning modeling career to become The Sentinel!
Co-starring Beverly D'Angelo as the masturbating neighbor,
and Jeff Goldblum as a young photographer.
