This movie is (as I type) number 119 on IMDB's top 250 movies of all time. It's very gripping, although it takes quite awhile to get going. Set in an isolated poor South American village, where (somehow) a group of foreigners have become entrapped without sufficient funds to get anywhere they want to be. Opportunity knocks when the evil American oil company about drilling 300 miles away hits a gas pocket, causing a well fire. And the only way to put it out is for our ragtag bunch to drive two trucks loaded with nitroglycerin over the treacherous route from the village to the drilling site.
The photography and staging of the trip is stunning. The acting is less so. Without giving too much away, the next-to-last shot of Yves Montand is kind of giggle-inducing, although that's certainly not the intent.
