An out-of-favor Scotland Yard inspector (Edmund Lowe) hunts a killer diamond fence--The Squeaker (Sebastian Shaw).

London's jewel thieves are under the thumb of a mysterious fence (Sebastian Shaw), who ruthlessly exposes any thief who crosses him. Desperate, Scotland Yard re-hires ex-Inspector Barrabal (Edmund Lowe) 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, played by Ann Todd). Interested parties: Larry Graeme (Robert Newton), cat burglar; his girl, sexy dancer Tamara (Tamara Desni); Collie (Alistair Sim), sardonic reporter. Then murder makes apprehension of the Squeaker urgent.—Rod Crawford <[email protected]>

A mysterious fence of stolen gems is hated both by Scotland Yard and the underworld. The first because he is elusive, and the second because he betrays those who will not sell to him at his own price. Inspector Barrabal (Edmond Lowe), once one of the Yard's smartest and most-respected men, but now a disgraced drunk, is given a chance to make a comeback by rounding up The Squeaker (Sebastian Shaw).—Les Adams <[email protected]>
