This film was made for British television in 1988, the last film by it's controversial creator Alan Clarke. There's no story here at all. Set in Northern Ireland, the film depicts a series of seemingly random killings.
It is shot entirely on location with completely unknown actors. The film is quite disturbingly realistic. There is almost no dialogue in the film and absolutely no attempt to give the film any kind of context.
The film is certainly well-made and impressive but the initial sense of shock fades before the film is over and the repeated images soon become dull, which might be the film's most disturbing aspect. In a way the use of gliding camera movements following characters either to their own deaths or to kill someone else, as well as the film's frequent use of holding on the image of the victims for some time after the killings take place can work against the involvement you might feel for this film.
It is certainly worth watching, however. The casualness of the brutality and the haunting images linger for a long time after the end credits roll
