Aidan McCrea and Kelsey, his wife, along with Aidan's brother, Rory, are joint owners of Star Sheep and Cattle Company. Aidan is the cattleman, bent on increasing his Black Angus herds and his acreage. He has political aspirations and hopes to one day become the Governor of Idaho. Rory McCrea raises sheep. Rory is black Irish and roguish which doesn't make Aidan happy. That Kelsey is attracted to Rory further adds to Aidan's dislike of his brother. The two brothers are often at odds on how to run their company. Rory considers Kelsey his "ideal woman" and that also causes friction between the brothers. After a major disagreement, Rory decides it's time to cut the ties and move to a Montana ranch, leaving Kelsey behind in Idaho. Can Rory find happiness on the new ranch and will his current love, Marta Lansdorf, finally displace Kelsey in Rory's heart?
