This is a film set in Glasgow… not nice Glasgow, but tower block hell Glasgow. The main character works as one of those people who look at close circuit TV images of the city, reporting any trouble to the cops. She has for unspecified reasons become very withdrawn from her fellow humans. Then she recognises someone from her past on one of the screens, and starts to track him, using the cameras to follow him around the city and then trying to insinuate herself into his actual life (oddly, he fails to recognise her, for reasons eventually explained).
The film cultivates a terrifying air of menace… when the protagonist crashes a party in the bloke's manky tower block flat, one is particularly expecting some kind of pay-off like something from a novel by De Sade. The film does however greatly misdirect the viewer, so the horrible events anticipated never quite arrive (at least not in the manner expected - I'm not completely giving away the plot here).
So yeah, if you would like to see a deeply uncomfortable yet brilliant film that will forever put you off moving to Glasgow, then this is the film for you. It also features the world's best chat up line: "I've been wondering what your cunt tastes like".
The tower blocks look pretty flash, I'm sure you agree.
