Tom Whitney, connected with the American embassy at Trendary, meets the Princess Alexa and promptly loses his heart. Sometime later the Princess goes shooting and accidentally wounds the young American who is passing through the woods. The injury is a slight one and the young people establish a bond of friendship which soon ripens into love. Tom is called back to America. He writes to Alexa, asking if she is willing to come to the United States and become his wife. The Princess decides to sign away her title and when she informs her father, the infuriated king locks her in her room, under guard. Alexa, however, escapes with the assistance of her maid and flees to America. At New York, Alexa is met by Tom, who drives her to a little church where a quiet ceremony is performed. The girl has had no time to secure suitable wardrobe and a visit is paid to the famous Lucile establishment, where many beautiful gowns are purchased. In Washington Tom lavishes presents upon Alexa and is soon in dire financial straits. He is approached by an international spy who induces him to copy certain secret plans. Tom is about to fall from grace when Alexa discovers the situation. By selling her jewels and paying Tom's creditors she thwarts the scheme of the spy and informs her husband, "I am no longer a Princess, just your plain American wife."
