Love, hate, jealousy, desire sometimes work together with disastrous consequences.
Kathryn Bigelow put together an interesting story based on a novel using these themes. Action bounced back and forth between the present with Catherine McCormack, Sean Penn, Elizabeth Hurley & Josh Lucas; and the past featuring Sarah Polley.
A murder took place in 1873 and there is no doubt watching the action that Polley committed it. Unfortunately, a man hangs for the crime instead of her.
The present day crew with McCormack doing a great job as a photographer investigating the murder seem to be having some of the same problems that beset Polley. Her husband (Peen) can't seem to take his eyes off Hurley (and who could blame him as she exposes ample skin to distract us should the story lag - which it doesn't), and there is some indication that more might have happened.
Just as things came to a head with Polley and a moment of madness overtook her, we can see the same things happening in the present.
The murdered are still be discussed 100 years later and only a couple of people know what really happened. We can also look at the present situation and discuss what went on in the minds of the characters in the storm. It leaves room for doubt, and that is what makes this an interesting story, besides, of course, McCormack's and Polley's performances.
