Murder!

Actress Edna Druce is found dead, and fellow thespian Diana Baring (Norah Baring) can't explanation why she's holding the murder weapon. Diana seems destined for conviction and the death penalty, but juror Sir John Menier (Herbert Marshall) thinks she's innocent. An actor himself, Sir John collects clues and revisits the crime scene in an attempt to clear Diana, but his noble efforts might finger another performer with ties to Edna and Diana's touring company.
