Nineteenth-century England, a time when the groundwork was being laid for a war over opium exports. McQueen Leicester, the head of England's largest trading company, 'Cloud Dieujian', and a major player in the opium trade, seeks to realize his ambition of seizing power by exploiting high society through war. At a salon he attends to lobby, McQueen encounters Aaron Wisfield, the libertine of London society. He comes to despise the man, whose refined exterior contrasts sharply with his eccentric behavior under the influence of opium.
