Bettina Vanderpoel, the charming daughter of New York millionaire Reuben Vanderpoel, departs for England to visit her sister Rosalie, who is married to Sir Nigel Anstruthers, an impoverished English nobleman. Arriving at their dilapidated estate, Betty finds that Nigel not only has wasted Rosalie's fortune, but has treated his wife and their little son cruelly. Betty promptly repairs the estate with her own money and then introduces her sister into English society. In the process, she meets Lord Mount Dunstan, a proud but penniless nobleman who lives in the adjacent estate. Although strongly attracted to Betty, Dunstan avoids her so as not to appear a fortune hunter. An epidemic breaks out among the farmers, and Betty, hearing that Lord Dunstan has died, goes riding late one night to forget her sorrow. Sir Nigel finds her in a deserted hut and tries to attack her, but Lord Dunstan appears, rescues her, and finally confesses his love. Soon after, Sir Nigel contracts apoplexy and expires, thus freeing Rosalie.
