In 1903, Doctor Huntington Bailey meets a friendly older lady during a train trip. She tells him that she is going to visit her brother Nick and his lovely young wife Allida. Once in New York, Bailey hears that his train companion suddenly died. Shortly afterward, he meets the strange couple and gets suspicious of Nick's treatment of his wife.

In 1890, two British expatriates, Robert Herrick and Huish, and German Captain Jakob Thorbecke, are commissioned to sail a Yankee schooner called The Golden State , whose captain and crew have died of smallpox. From Tehua in the South Seas to Australia, they are to deliver a cargo of champagne. Thorbecke decides to head for Peru, however, so he can sell the merchandise and pocket the money. While sailing, Faith Wishart, daughter of the deceased captain, comes out of her hiding place on board and, by briefly holding Thorbecke at gunpoint, demands he make the delivery.
