The Wages of Fear (Le Salaire de la Peur)
1952

Set in a small oil town in the middle of nowhere, some of the men get a chance at a way out, but at what cost? There are four openings to transport an fragile and explosive payload across the desolate and rugged countryside. Truly a must see!

A quote from film critic Roger Ebert:

One thing that establishes THE WAGES OF FEAR as a film from the early 1950s, and not from today, is its attitude toward happy endings. Modern Hollywood thrillers cannot end in tragedy for its heroes, because the studios won't allow it.
