The Crown Prince's Double

Prince Oscar of Ostrau, about to marry a princess from a neighboring country to please his father, King Gustave, is saved from that fate when an uprising causes the princess to leave. After Prince Oscar indulges in a dalliance with a burlesque actress in London, England, King Gustave arranges for his American friend, Peter Hart, to take Oscar to the U.S., where Oscar marries Peter's sister, Isabelle. The wedding news, coming as the king returns to the throne, causes him to send his chief of police, Baron Hagar, to have the marriage annulled and return the prince home. After Peter, Isabelle, and Oscar escape from the baron, they discover an unemployed clerk, Barry Lawrence, who looks just like Oscar. They give him $1,000 to lead the baron off their trail, but when Barry's sweetheart, Shirley Rives, thought to be Isabelle, is endangered, Oscar reveals himself to the baron and refuses to return. He then renounces his claim to the throne and becomes an American citizen.
