Spuds.

In France during World War I, an army payroll car containing $250,000 turns up missing. A GI, nicknamed "Spuds" because of his prowess at peeling potatoes, discovers that it was stolen by German spies, and--since his captain was responsible for the car and will be in big trouble if it's not recovered--goes behind the enemy lines to retrieve both the car and the $250,000 payroll.
