On a train traveling from the West, Grenfall Lorry, an American (Eugene O'Brien), meets the mysterious and beautiful Yetive (Norma Talmadge). By the time they reach their destination of New York, they are deeply in love, but Yetive is called back to the European principality of Graustark where she lives. Lorry follows after her and discovers that she is a princess who is being pushed into a loveless marriage with Gabriel, a neighboring prince (Marc McDermott). Gabriel sends his henchman Dangloss (Roy D'Avey) after Lorry, who wounds him in a battle. Dangloss is spirited out of the country and the American is accused of murder. He is convicted and sentenced to death, but Yetive helps him to escape. At the border, Lorry finds Dangloss and brings him back just in time for the wedding ceremony between Gabriel and Yetive. Gabriel is disgraced, and Yetive's desire to wed Lorry wins the approval of her countrymen. ~ Janiss Garza, Rovi
