When 4 American tourists - Sofia, Carl, Belle and Michael - go on a ghost tour, they get much more than they bargained for, when the ghosts of an evil Doctor and his last patient victim trap them in the old abandoned psychiatric ward.
For Gothic Callie, her deaf sister Ariel, computer nerd Chris, popular Sarah, and misogynist Ricky, their evening plans are about to be re-written. Taken to an abandoned military training school, they finds themselves the target of 5 sadistic killers, each with their own unique and different style of killing. They fight for their lives against sociopaths who know their environment intimately, becoming increasingly outnumbered as their friends are killed.
Three men are reunited after 30 years by the echoes of a terrible crime. Old men now, and at the end of the line they are intrigued to meet a young girl named Sarah. Through her they are plunged back into the sordid (and hilarious) belly of Australia's underworld, both past and present.
