In a stylized, neon-drenched New York City, Margaret, a cynical and ambitious fashion model, shares a chaotic loft with Adrian, a cold and detached German
fashion photographer. Their decadent lifestyle of drugs, art parties, and
sexual experimentation is disrupted when a small, flying saucer lands on their roof. Piloted by an invisible, parasitic alien entity, the craft brings an extraterrestrial presence into their lives that feeds exclusively on the human brain chemicals released during orgasm and heroin use.Unbeknownst to Margaret and Adrian, the alien quietly attaches itself to Margaret. As it feasts on her neurological releases, it grants her a lethal power: anyone who achieves sexual climax with Margaret is immediately vaporized, leaving behind only a fine, glowing pink powder.Meanwhile, a frantic scientist named Dr. Penelope is obsessed with tracking the UFO. Recognizing the alien's presence in the city, Penelope attempts to warn authorities and society, but is largely dismissed as unstable, driven by a desperate need to understand and capture the extraterrestrial visitor before it consumes too many lives.Margaret remains largely oblivious to the lethal consequence of her encounters. Driven by narcissism, boredom, and a desire to climb the New York social ladder, she continues to engage in a series of promiscuous trysts. With each romantic or sexual liaison, her partners meet a gruesome and sudden end. Among the victims are her photographer roommate, various arrogant socialites, and rival models. Instead of feeling horror, Margaret grows increasingly empowered by her new status as an untouchable femme fatale, viewing her deadly condition as the ultimate expression of her autonomy and dominance over a predatory, shallow subculture.As the body count rises, the city’s nightlife descends into a paranoiac panic. Detective Malone investigates the bizarre disappearances of the pink powder victims, closing in on Margaret's loft. Simultaneously, Dr. Penelope finally locates the source of the alien energy signature.In a climactic confrontation, Penelope attempts to sever the connection between Margaret and the alien parasite. Rejecting the doctor's warnings and the police intrusion, Margaret makes a final, fateful choice. Rather than relinquish her newfound, god-like transcendence, she embraces the alien entirely. In a brilliant flash of neon light, the spaceship returns to the roof, and Margaret boards the vessel, leaving behind a baffled police force and ascending into the cosmos as an immortal, alien-infused entity, escaping the bleak reality of Earth forever.
