Synopsis by Janiss Garza
American engineer Robert Maury (Conway Tearle) travels to Paris with his wife, Elsie (Dorothy Mackaill). He leaves her there while he goes to Argentina on business. Elsie, like most neglected wives (at least in films), uses this opportunity to get into mischief -- she dresses exotically and draws the attention of Spaniard Don Arturo (Richardo Cortez). She goes to visit Arturo at his estate and his ardor is so passionate that she decides to write her husband a "Dear John" letter. Arturo is killed by a man who is infuriated because he ruined his daughter, and Elsie returns to Paris. When she discovers the letter hasn't arrived yet, she goes with Maury to Argentina. Arturo's servant, Juan Serafin (Lon Chaney) tracks her down with the letter. Elsie confesses all to her husband and insists that he read the letter. When they open up the envelope, it only contains a black sheet of paper -- the original has been destroyed. Maury forgives Elsie, and husband and wife are reconciled.
