Set amidst the tense and suspenseful world of men who transport large amounts of nitroglycerin, used to put out fires in oil fields, this drama centers on the conflict between a young med student, who has become a nitro handler to help pay his way through school, and the old trucker who hauls the deadly chemical on site. The trucker resents the young man's attentions toward his daughter because he feels that there can be no security with a man who could accidentally blow himself up at any moment.
