Based on Daniel Defoe's 1722 novel of the famed English adventuress Moll Flanders (Kim Novak). Moll is first engaged as a maid by an eighteenth-century English family chiefly composed of sex-starved males. She marries the imbecilic second son, who prefers booze to copulation. Too embarrassed to speak the truth of him, she demurely tells friends, "Modesty forbids me to reveal the secrets of the marriage bed". She then meets a rich banker (George Sanders), becomes maid-companion to a Count (Vittorio De Sica) and his Lady, and finally weds the banker, but leaves him on their first night together. She then joins a group of thieves, falls in love with James "Jemmy" Seagrave (Richard Johnson), and becomes their number one asset before she is sent to prison. After she is released, she finds Jemmy, and, in the end, everyone is on an America-bound boat except the banker, who fortuitously dies of a heart attack before he has had an opportunity to alter his will.
