A wealthy man is shot just as he reaches for the phone to call for the police. Suspicion falls on his ward (Lila Lee) as he has intended to change his will, which had left his entire estate to her, to share it equally with his nephew. The nephew, who is in love with Lee, calls in a private detective, who eventually finds it is the lawyer who is the criminal.
