It's "Never the Twain Shall Meet" time again in the MGM romantic melodrama Lady of the Tropics. The lady in question is half-caste Manon De Vargnes (Hedy Lamarr), a resident of prewar Saigon. American playboy Bill Carey (Robert Taylor) falls madly in love with Manon, but both have their crosses to bear: she is affianced to an Indochinese prince, and he is unable to secure a passport to bring her back to the United States. Adding to the dilemma is influential bureaucrat Pierre Delaroch (Joseph Schildkraut), who agrees to arrange an exit visa for Manon in exchange for a few "favors." Nothing good can come from this, and nothing does.
