you won't be disappointed. The set-up is very slow and plodding, but the last hour is one of the most atmospheric and tense I've ever seen. I really felt for Jane after she loses her friend while on a biking holiday in France. I was annoyed at first, but then glad, that there are no sub-titles for the French speaking people. Jane doesn't speak French well either, so her helplessness and frustration translated to me extremely well. I felt her situation was very real. The story keeps you guessing about who to trust and who not to trust. Also, the whole movie takes place in one day during the daytime, so the title takes on extra meaning as Jane tries to find the truth. As darkness approaches, she loses more and more hope her friend is alive. Its really cool. I give it 8 out of 10.
