It's sort of a wilderness chase drama. FBI man Sidney Poitier (somewhat elderly - he was 61 when this was filmed, although he doesn't look it) follows jewel thief, kidnapper, murderer and all round bad guy Clancy Brown from big city to Canadian border, tracks him over the mountains (with a bit of help from mountain expert Tom Berenger) and catches up with him in Vancouver.
It's not bad, although the action sequences do seem a bit contrived and it's a bit stilted at times. The scenery is magnificent (it was filmed in Canada) and provides an excellent backdrop to the story, which does unfortunately have a rather silly ending as Mr Poitier (chasing his man in Vancouver as a foreign cop with no jurisdiction) survives several bullet wounds.
I enjoyed it (although it's not up to the standard of another wilderness drama that I saw recently, 'The Edge') and I'll give it 4/5 stars, although that does seem a bit generous.
