"Who's hand writes these messages of death?"
London's jewel thieves are under the thumb of a mysterious fence, who ruthlessly exposes any thief who crosses him. Desperate, Scotland Yard re-hires ex-Inspector Barrabal who, as a known drunkard, is ideally suited to go undercover with a faked criminal record (which may spoil his chances with lovely Carol Stedman).
