In 1855, Edward Pierce plans to do something that has never been done - rob a moving train. His target is the monthly shipment of gold destined to the Crimea for British soldiers who are there fighting the Russians. The ?25,000 in gold is stored in two locked Chubb safes that requires four separate keys to be opened. One key is held by the President of the bank; the second by its senior manager; and the two remaining keys by the station master. Along with his accomplices, Agar and Miriam, he sets about acquiring each of them. Once in hand, they must now find a way to break into the luggage compartment where the safes are located, off-load the gold and then go about their merry way without being caught. It doesn't quite go as planned but a good thief always have a back-up plan.
