Quayle and Gabor are an American couple in London posing as honeymooners; in reality they are secret agents out to get top secret information. Gabor turns up dead with all the accusations pointing toward Quayle. Neagle plays the counsel appointed to defend Quayle, and he runs into difficulty because Quayle is unable to disclose certain information. The screenplay was written by writers well versed in litigation, so the courtroom scenes have a strong sense of realism. The performances are convincing, though marred by several characters who don't fit in the plot.
