On St Valentine's Day 1900, three schoolgirls and a teacher from an exclusive English-style boarding school go missing at the mysterious Hanging Rock in central Victoria. One of the girls is found alive a week later, but the others are never seen again. As morale within the school begins to disintegrate, the headmistress's increasingly incoherent anger is turned towards one student, leading to tragic consequences. Although the police suspect Michael Fitzhubert, a young English aristocrat, and his manservant Albert, who were in the area at the time the girls disappeared, the mystery is never solved. As Paul Byrnes (Australian Screen) notes, the suggested scenarios range from the 'banal and explicable (a crime of passion) to deeply mystical (a crime of nature).'

'Australia, 1900. An ancient land becomes the site of an impossible mystery. A group of schoolgirls and their teachers venture out into the sundrenched landscape, only for four of their number to disappear forever.

'The subsequent investigation creates more questions than answers. One of the girls is found with no memory of what happened to her or her classmates, another succumbs to hysteria for no apparent reason. Those close to the missing girls begin to meet with unfortunate ends and it becomes clear that this is no ordinary disappearance.' (Production summary)
