Daphne Carrol, once a "plain Jane," returns from Paris a "polished" flapper, and finding that her love for Custis Lee, her sister's brother-in-law, is not reciprocated, sets out to win him. His brother, Jack Lee, managing editor of the local newspaper, orders a conspicuous report of Daphne's return, but through an error her picture appears over a news item citing the escape from an insane asylum of Sally Long, bent on revenge on her husband. Daphne gains entrance to Custis' house and poses as Sally, disclaiming him as her husband. Fearful of his life, he humors her until he can engage a nurse to watch her. Daphne enjoys the joke until she discovers that her nurse is actually Sally--and Sally's husband tries to rob the Custis home. In the merry mix-up Daphne faints in Custis' arms and is forced to declare that she is his wife; after the complications are resolved, they decide to make the arrangement legal.
