Edith Vandiwert and her aunt are visiting Atlantic City, where Edith is the object of the attentions of a bogus count, who presses his suit ardently. Edith, however, prefers Arthur Dore, a wealthy young American, who is interested in hydroplaning. The count steals a valuable necklace, and manages to place the blame upon Arthur, who is disgraced. But in seeking to force the girl into a marriage he abducts her. Arthur gives chase in his hydroplane and, after the rescue, explanations heal the breach and cause the arrest of the fictitious nobleman.
