Jindabyne
A 2006 Australian movie filmed in and around the real life Jindabyne, nestled in the Snowy Mountains of New South Wales.
An annual fishing trip between four friends is marred by the discovery the corpse of a young woman. Rather than going into the details of how and why the girl was murdered as the opening scenes suggest, this film deals with the bleak consequences of the four men not immediately reporting the crime (instead they wordlessly agree to continue fishing and tie her corpse down so it's not lost to the rapids).
As police investigations ensue, the deceased, Susan, is discovered to be of Aboriginal descent; this gives rise to awkward race-relations between the local Aborigines and the white Jindabyne residents. In particular, Stewart (who made the decision to tie the corpse down) finds his world collapsing as before the fishing trip, his relationship with the mother of his son, Claire (who abandoned the family for 18 months after having a nervous breakdown) and mother-in-law was rocky at best.
This was a very sombre, but very human film, examining how fragile relationships can be. Also, in the grisly light of reality, this film explored just how complicated, difficult and inexperienced human beings can be when faced with the consequences of their actions (or inactions).
Unlike most movies, there wasn't really a clear beginning, middle or end like a story --- rather, this was filmed as a glimpse into the lives of the people involved, just before the incident and dealing with the aftermath of it. The ending is ambiguous as the Aborigines finally bid farewell to Susan. Nevertheless, the acting was brilliant throughout.
Definitely something to make you think... (though maybe the film's matter was brought into sharp relief as I suffered a bereavement of my own all too recently at the time of writing this).
