Incidentally, if no one objects, I'd like to completely delete the synopsis for this film including at the bottom of the DB listing. It spoils nearly every major and minor plot twist in the movie, so much so that rewriting it would be a waste of time. The film isn't a whodunnit, per se, but there are, as in any good film, a number of interesting plot and character turns, and nearly every single one of them will be ruined if anyone reads that summary before watching the film.

From the looks of it, it was taken from the back of a DVD or perhaps the film or DVD website. It really shouldn't be here.
