British Army captain Geoff Roberts carries on an affair with Alva, the wife of the cruel Victor Sangrito. Sangrito, however, is well aware of the affair, as he uses his beautiful wife to lure men into romance with her, then blackmailing them to save their careers. When Roberts falls into Sangrito's trap, he pays the blackmail and leaves for India, hoping to forget Alva, whom he loved but now believes betrayed him. After some time in India, he is joined by his young friend and bosom companion Lt. Ned Nichols. Nichols, too, is in love with a woman back in England...the same woman. Though the two friends nearly come to blows over Alva, they eventually realize that she has been false to them both and that their friendship far outweighs their feelings for a mendacious woman. But when the two are invalided home, they encounter Alva again, and learn that she may not have betrayed them after all.
