They Met in Bombay is a typical MGM star vehicle, in which the leading players are called upon to carry a pencil-thin plotline on the force of sheer personality. Clark Gable and Rosalind Russell play Gerald Meldrick and Anya Von Duren, a pair of rival jewel thieves at large in India. Both parties are after the same prize, a priceless diamond owned by the Duchess of Beltravers (Jessie Ralph). To inveigle their way into the Duchess' confidence, Gerald poses as a Scotland Yard detective, while Anya pretends to be an aristocrat. After several reels of cross-purposes, hero and heroine decide to team up, keeping one step ahead of a diligent police inspector (Matthew Boulton) and mercenary freighter captain Chang (Peter Lorre). Both Gerald and Anya betray the nobler sides of their natures in the final reels, participating in a pitched battle against invading Japanese military forces.
