BIG RIG is a portrait of modern America as seen through the eyes of long-haul truck drivers. Spanning 21,000 miles, 45 states, and dozens of truck stops, this film delves deeply into the lives and struggles of these working-class heroes, who literally carry the nation upon their backs. Drivers face skyrocketing gas prices, government interference, corporate take-over of their industry, and a highly unsympathetic public full of "four-wheelers" who more often give the finger than the right-of-way.
