One of tha all time great movies is on a similar theme. It’s a French movie (I know I know) made in the early 1950s called The Wages of Fear. It’s about some truckers stuck in some South American town and they are offered big bucks to take some nitro over bad roads to some oil well fire to help put it out. The tension and suspense in this movie is supreme. Highly recommended if you can somehow find it.
The American version of this was “Sorcerer” (1977) with Roy Schider. I saw it when it first came out.
