A rocket plant must be relocated after a deadly accident. Trucker Mitch Barton (Brian Keith) recruits a team for a suicidal job: to drive three trucks carrying extremely hazardous chemicals (nitric acid, hydrogen peroxide, and hydrazine) over a treacherous mountain road in just three days for $5,000 each. The rocket fuel developer, George Lawrence (Efrem Zimbalist, Jr.), joins the group to ensure safety. The mission suffers a tragedy and nearly fails when one driver, Frank Miller, dies from chemical burns after heroically preventing an explosion. After overcoming breakdowns, fatigue, and other dangers, the surviving men have a chance to reexamine their lives, while completing the delivery.
