Based on a popular drawing-room drama by Frederick Lonsdale, The Last of Mrs. Cheyney stars Joan Crawford as a jewel thief who poses as an aristocrat. It is Crawford's intention to pilfer a valuable pearl necklace while attending a society party in the company of partner-in-crime William Powell. Here she attracts the attention of Robert Montgomery, a young nobleman who is amused by Crawford's wittiness in the face of the haughty bitchery of Benita Hume. When Montgomery turns out to be a bounder and Powell and Crawford are revealed to be criminals, Crawford does some quick thinking that not only gets her off the hook but puts the two-faced Montgomery in his place as well. Previously filmed in 1929 with Norma Shearer in the lead, The Last of Mrs. Cheyney would itself be remade in 1951 as The Law and the Lady, with Greer Garson as the heroine.
