A retired Argentinian federal agent writes a book based on his recollections of a 25-year old unsolved murder case. Darin and Villamil give good performances as government co-workers whose relationship is fraught with unconsummated sexual tension. It is an intriguing story, but the execution is sloppy. There are too many loose ends and the plot elements pertaining to the murder suspect are so ludicrously contrived in terms of how he is targeted, caught, and convicted that it's hard to take this film seriously. Furthermore, after all the buildup, the conclusion is rather underwhelming. It's not a bad film by any means, but it falls far short of its lofty reputation.
