On the night of August 14th, 1775, two dozen men sneak through the streets of St. George's in Bermuda, right under the British governor's nose. Only guided by moonlight, they trek to the top of a hill and face a stone building. Carefully and quietly, they chisel their way through the roof and send a man inside. What waits for him is over 3,000 pounds of gunpowder. They carry the barrels out to sea onto waiting ships. Their destination: Philadelphia. This is the heist that paved the way to victory in the Revolutionary War.
