In comfortable dotage, baronet Humphery Tavistock (Laurence Harvey) recalls a lifetime of romantic entanglements to his wide-eyed son-in-law. Tavistock has come to the conclusion that women are a riddle wrapped in a mystery surrounded by an enigma, and his reminiscences bear this out. Among the baronet's many amours are a suffragette, a harem girl, the wife of a diplomat who "demands satisfaction", an American heiress, a bohemian artist and an army nurse. After all this, Tavistock finds lasting happiness with the first women he ever loved. The female cast of The Truth About Women features the illustrious likes of Julie Harris, Diane Cilento, Mai Zetterling and Eva Gabor, so it's little wonder that the hero has so many vivid memories to fall back on.
