George Lester, the Duke of Northumberland, flees familial expectations in Britain for the promise of freedom of San Francisco, looking for the chance to be himself. But before he even gets close, a blizzard forces him off the road, and he finds himself freezing half to death in a small town with no motel… with a litter of puppies to look after.

Luckily for George, he also finds Alan.

As the heir to his family's ranch, Alan Justice knows the burden of being the oldest son. He doesn't have time to show George, the stranger his brother dragged home, what it takes to be a cowboy. But that very night, George surprises him by helping a mare in distress through a difficult birth. Maybe the duke is made of sterner stuff than Alan thought.

George and Alan keep surprising each other, and every day they grow a little closer. But when George's responsibilities call him home, Alan finds he's the one who has something to prove—that he can handle what it means to be the duke's cowboy.
