The stranger strangler has been brutally murdering homeless girls near the run-down old cinema where Tom Burden works. The shelter next-door is a magnet for the young and vunerable, and the serial killer who's stalking them. Late at night in the cinema, Tom's plagued by unexplained noises-the old organ starts playing by itself, lights are mysteriously switched off. Worst of all there's the terrifying whispering and wheezing that haunts him in the darkness-the sound of someone struggling; of someone dying to breathe.
