Plot.
As described in a film magazine, Lord Allan Harrowby (Elliott), upon arriving in America to wed an heiress, goes to the New York office of Lloyd's of London and insures against the lady changing her mind. Dick Minot (Washburn), assistant manager of the office, is assigned to the task of preventing that occurrence. He meets Cynthia Meyrick (Wilson), the lady in question, but not knowing her identity falls in love with her. However, business is his first thought and when she decides that she does not love her fiancé and is about to break her engagement, he does all in his power to bring about the wedding. This involves defeating a stranger who claims to be the real Lord Harrowby, outwitting a customs official who seeks to arrest the nobleman for smuggling in a diamond necklace, the routing of a clever criminal who tries to steal the necklace, and effecting the dismissal of a young woman who threatens a suit for breach of promise. After all this is effected and the wedding about to proceed, Cynthia again changes her mind, but this time it is because of an act by Harrowby. By the terms of the policy, this releases the company, so Dick presents his own case to Cynthia, which she accepts and they elope.
