In September of 1777, General Washington and his troops are encamped just north of Philadelphia. The war is not going well for the Continental Army, the British are closing in fast and, worst of all, there is no money to pay the discouraged troops. Twins Sally and Roger are asked by their father, General Priestly, to help their mother hide a shipment of gold which will be used to pay the American soldiers. Unfortunately, British spies have also learned about the gold and will stop at nothing to prevent it from reaching General Washington. Mrs. Priestly and her children must act quickly to keep the gold hidden and deliver it safely to the waiting army. Based on a true story, this is a thrilling episode from our nation's history!
