Chacun Sa Nuit ("To Each His Night") is a modern study of French teens which turns into a murder mystery. Narrated by the lone female in a quintet of very close friends, her narcissistic, bisexual twin brother ends up dead and she is bent on solving the crime. Rather than a whodunnit movie, in which the audience has clues, here all we can do is go along for the ride -- trying, with the sister, to unravel what happened and why. Contains non-sexual nudity, some sexual content and profanity.
