Aiming to reach a larger market, Tavish and his brothers need an infusion of cash for their whisky distillery in the Scottish Highlands. An elderly uncle suggests they seek brides with large dowries. The only place they'll find such heiresses is London, where he has long-lost relatives. Tavish goes along with the idea, although his worst nightmare is the same kind of unhappy, loveless marriage his parents endured.

Piper Graham's mother intends that her daughter marry the duke who has expressed interest in wooing her. Granddaughter of a Scot, Piper is enamored with all things Scottish and longs for passion in a relationship. She has no amorous feelings for the duke, who happens to be Tavish's cousin but falls for Tavish the moment she sets eyes on him, much to the chagrin of her ambitious parent.

Piper is from a well-to-do family but marrying her won't bring the family business the cash it requires, no matter that Tavish falls in love with her. Things become more complicated when the Prince Regent gets involved.
