A murder mystery drama set in the northern Alaskan summer, where the sun is out 24 hours a day. Al Pacino plays a sleepless detective on the case of a teenage girl who was brutally beaten to death and then carefully manicured in ultra-creepy fashion.

Initially, the style of the film almost reminded me of an R-rated version of a typical Millennium episode. Directed by Christopher Nolan of Memento fame, it definitely bears his trademarks style, using subliminal frames (many of which I noticed the existence of, but could not consciously parse), characters whose past memories are hauntingly ambiguous, and some wild plot twists.

Hilary Swank is also in the movie, this time she plays a female character (to what am I not refering?) -- a younger police investigator who looks sees Pacino's character as a hero, a legend in the academy.

The movie really gets interesting when... well... I shouldn't spoil it. (And shame on imdb for putting spoilage right into the plot outline on the main page. I'm glad I didn't look at it prior to watching this film.)
