As a young widow with futures to secure for her two daughters, Glenda McKinley is torn between remaining at her beloved estate Pinmuir in the Scottish Highlands, or following the plans her deceased husband made to join his brother in America. Though her inclination is to stay among all that is dear and familiar, she is forced to reconsider when her daughter Caitlin's health takes a turn for the worse and the family doctor suggests a change of scenery would do her good. The family's imminent departure for Colorado comes as a blow to Ros, the eldest girl, who has fallen in love with Clive, son of their estate manager. For her sister's sake, however, she agrees to try life on her uncle's cattle ranch and the family travel half the world away to start anew. America is a whole new world to the McKinley family, and in spite of the hospitable welcome they receive from Gordon McKinley, the scale of the country and hard realities of ranch life come as a shock to the family who pine for the things and people they left behind in Scotland. When a gentle, unassuming cowboy falls for Glenda, she has a strong incentive to stay and make a new life. But with Ros yearning for the man waiting for her back in Scotland, can the family ever find true happiness when each must pursue a different dream?
