Two young couples turn up at a supposedly haunted house for the weekend where they are met by a third. That sentence may contain a paucity of detail but, regardless of how much it is elaborated on, you know what comes next.
The house concerned is actually an abandoned hospital in Australia where a notorious doctor used to practise shock therapy. The third couple are the custodians, and for a fee they will show you around the premises where you can experience the feel like no other haunted house in Australia complete with cold spots nurtured by dry ice.
Yes, to the surprise of the custodians and the disbelief of the paying customers, a real spirit is unleashed, and yes, it does start killing them, and yes, this is not the sort of situation in which any rational person wants to find himself. The ghosts are rational too, one of them, because in the penultimate scene, having possessed the body of one of the people she/it hasn't killed, she explains at length to the other survivor how wrong he is about ghosts. Does this film have any good points? Well, at the moment you can watch it free on YouTube, but you may still want your money back. The reasons "Ravenswood" doesn't score zero points are because one is mandatory and because all concerned are clearly rank amateurs, and should not be judged by the standards of professional actors, scriptwriters or producers. In short, pity.
