A glowing spaceship appears over the New York City skyline as dissonant New Wave music fills the multiple ears with their dangling rings. Junkies, models, poseurs and performance artists feed off each other in a battle to be the most fierce, all the while unaware that tiny aliens are harnessing their ecstasy. Most visitors to New York go to Serendipity for a frozen hot chocolate — these buggers are literally fueling their space ship with the power of the human orgasm, which turns the screen electric blue and red and green and purple.

“Liquid Sky” is set in New York City in the few years between disco and AIDS when young denizens indulged in exhibitionistic sex and hard drugs and took their fashion cues from the gleefully androgynous English New Romantic movement (big hair, frills, ruffles, theatrical make up). They danced like rusty robots in neon lit nightclubs. Within this odd demimonde Margaret (Anne Carlisle) lives and works as a successful model. She has the perfect life, with one exception: she kills everyone she has sex with, whether that sex is loving, non-consensual or even with her male doppelganger “Jimmy” (also played by Anne Carlisle, then a face at the Mudd Club, a key hangout of the period). Margaret is high maintenance (“You know this bitch takes two hours to go get ready to go anywhere,” says girlfriend Adrian, who nearly steals the film with her performance of “Me and My Rhythm Box”).
