A courtroom drama, it sees an American scientist charged by the British police for his supposed role in the death of a secret agent who had been posing as his wife.

The attention given to legal procedure is, it must be admitted, exact and authoritative; but motivation is generally rather hazy, and the predicament of the central character is rather incredible.

Anna Neagle is in fine form, however, as Britain's foremost Queen's Counsel, and carries off her big courtroom speech with impassioned determination.

"[5] The Radio Times wrote, "courtroom dramas have an intrinsic appeal, and veteran producer/director Herbert Wilcox makes a moderately entertaining film out of this story in which Anthony Quayle's American scientist, accused of murder, refuses to testify in his own defence.

Wilcox's wife, Anna Neagle, gives another of her great lady portraits as Britain's leading Queen's Counsel, demonstrating her deductive brilliance in spotting a bullet hole in a witness's window pane and her oratorical skills in a dramatic five-minute courtroom address.
