Espionage, war and romance in the Far East in 1904: Russian naval officer Boris Ranewsky marries Youki, the sister of a fanatical Japanese officer, but war is imminent.

The lawyer, Dr. Werkmann, is seeking a legal separation for Mr. Bernhof, who claims his wife is an incorrigible gambler. In reality, it is he who is the weakling; and while he dearly loves his wife, he's going through her fortune like there's no tomorrow. His wife, however, loves him dearly, too, in spite of his faults and doesn't want the marriage to end. Dr. Werkmann proposes something at a family meeting, which just might save the marriage after all.
