Her desire for adventure causes Florence to aid her father in smuggling diamonds into this country. Meeting Robbing, a customs inspector, the girl falls in love with him. The two are eventually married. Secret Service Agent Ellen is led to suspect Cole and Florence. A visit to Stoddard, a jeweler, confirms this suspicion. Shortly afterward, Cole informs Robbins of his desire to have Florence accompany him abroad. U.S. agents in Paris trail the suspects and learn that Cole intends to smuggle a large number of gems. When the two return to these shores Ellen has them searched. This search proves fruitless. Upon entering her home an hour later, Florence places a box of candy she has carried all along, upon the table. Robbins carelessly takes one of the chocolates and bites into it. Then comes the discovery that each piece of candy contains a smuggled gem. Horrified, the inspector spurns his wife's explanations. Hastening to his chief, the boy gives him the candy containing the smuggler's gems and tells him the story. Florence enters the Deputy Collector's office in time to see her husband place his resignation in his chief's hand. Florence's grief touches the Deputy Collector's heart and he tears up Robbins' resignation. Realizing that his wife's repentance is sincere, the young man forgives her.
