What Is The Plot Of The Film 'The Edge'?

One of my favourite, not entirely successful films, it has some great lines and has Anthony Hopkins swearing, which is always fun.

Wealthy millionaire Charle Morse (or Morris) it's hard to know with the US accent and his trophy wife (she's a model) Micky, are having  combining a get away in the wilderness of America/Canada with a photo shoot.  They've brought along a photographer and some assistants.  When Charles, his pilot and the crew set off to find an old native american friend of the lodge keeper, their plane has a bird strike (birds hit the propeller) and they crash in the freezing cold lake.

The film now follows the course of Steve (the assistant),  Bob the photographer and Charles as they try to survive against the elements, a killer bear and each other.  I'm not going to spoil the plot entirely, but it soon becomes man against man, age against youth, the city versus the country.
