Five years ago, a budding artist named Anita Gregory found it necessary to place her twin sister Susan in a mental institution. When Susan escapes, she calls on her sister, meets her in a lonely locale, knocks her unconscious, changes clothes and purses and drives away in her car. Anita is found by Sheriff Wiley and taken back to the institution where everyone thinks she is Susan. When Anita warns them that Susan is likely to commit murder, the authorities still won't listen to her.
