In the midst of an ever-mounting Civil War, Major General Lee Blake is summoned to spearhead a mission of utmost importance to the Union cause--the transport of an invaluable shipment of silver from the Comstock. Aided by his long-time friend and wagonmaster Whip Holt, Whip's courageous son, a beautiful sharp-shooting newswoman and a seductive courtesan, the vital journey begins. But the task is fraught with danger and adventure as Confederate saboteurs and cunning British agents will stop at nothing to prevent the "silver train" from reaching its destination.
