Erma Desmond (Ruth Roland) leaves her uncle and aunt to visit a friend, Phyllis, in the city. There, she finds work as the companion to the highly temperamental Mrs. Stanley (also played by Roland). Mrs. Stanley has terrorized her husband (Andrew Arbuckle) to such an extent that he has gone away for a few months, purportedly to take their daughter to school, but mainly to get some peace. The servants, however, are still victims of her terrible fits until the day she decides to head for Reno to get a divorce. Because of their resemblance, Mrs. Stanely leaves Erma to impersonate her while she is gone, and the servants are puzzled at their mistress' sudden personality change. Not that they mind, since Erma is as sweet as Mrs. Stanley was horrible. Confusion reigns, however, when a friend of Mrs. Stanley's shows up at the same time Phyllis does. It gets even more complicated when Mr. Stanley comes home and finds himself falling in love all over again with the woman he believes is his wife; Erma, meanwhile, returns his affection. Finally, a telegram arrives from Reno; Mrs. Stanley has gotten her divorce, and Mr. Stanley is free to marry a new Mrs. Stanley.
