When a group of schoolgirls from an elite Victorian finishing school embark on a Valentine's day excursion to an unusual outcropping of volcanic rock, four members of the party are drawn towards the summit, where they experience powerful forces of time, nature, and eroticism, and vanish into thin air. This meticulously crafted Australian film displays a remarkable sense of eerie foreboding and lush surrealist sensibility, which have earned it a rabid cult following.
