Storyline:

A convoy of trucks driven by four derelicts transports dangerous nitroglycerin to try and quell an oil well fire. Their long, harrowing ride over bad roads with their cargo ready to explode at every jolt and jar; the drivers are gambling with their very lives against the opportunity to escape from their steaming, sordid environment. Remade in 1977 by William Friedkin (following "The Exorcist,") as "Sorcerer."
