Valentine's Day, 1900... a beautiful day for an excursion to aboriginal holy place 'Hanging Rock', the perfect place for a school picnic. Amongst the young white gloved pupils of Appleyard College are senior boarders Miranda, Marion, Irma and Edith. All are properly chaperoned by headmistress Mrs Appleyard and various members of her teaching staff. When the four girls venture off to walk to the lower slopes, distant screams are heard and eventually, Edith returns, panic stricken and alone .... A search is organized and witness interrogations follow but Edith remembers nothing. What eerie events took place that day, and will those involved ever rid themselves of the demons that the ill fated picnic unearthed?
