A drug-fuelled teenage joyride is the unlikely catalyst for this modern horror with a social conscience. Foster survives the car crash which kills her boyfriend, but going back home to a Glasgow tower block fails to provide the expected rest and recuperation. Moving furniture and strange noises suggest the presence of poltergeist activity, but could it just be the disturbed aftershocks on a young mind? Buttle is the hard-pressed mother and Connery the cynical tabloid journalist on the case, as medical and eventually spiritual help is called on for answers. It may not quite have enough story to go round, but the film makes its point about the demoralisation of the urban disenfranchised while delivering a fair quotient of chills. Excellent use of suggestive sound and an impressive action finale, all done on a tiny budget.
