When an explosion at an oil well threatens hundreds of lives, a crack team is called upon to make a deadly desert crossing with nitroglycerine in tow.

Four men from different parts of the globe, all hiding from their pasts in the same remote South American town, agree to risk their lives transporting several cases of dynamite (which is so old that it is dripping unstable nitroglycerin) across dangerous jungle terrain.

In a run-down South American town, four men are paid to drive trucks loaded with nitroglycerin into the jungle through to the oil field. Friendships are tested and rivalries develop as they embark upon the perilous journey.
