Cocktail Hour (1933)

Cynthia Warren, independently wealthy through her ability as an illustrator and poster artist, rebels against the premise that every woman is destined for matrimony and motherhood, and decides she has as much right as a man to play around sans benefit of marriage. So, leaving behind steady-but-dull Randolph Morgan (who seems to be the primary buyer of her 'art' and income,) she heads for Paris. The New York harbor is barely out of sight before she falls into the arms of a slick from England,William Lawton, who turns out to be something of a rotter who already has a wife, and Cynthia's liberal creed only stretches so far. In Paris, she hooks up with a Prince, who is a prince of a fellow and never strays far from his mother's side, but Lawton shows up again and makes some unwanted advances and the Prince comes to her aid, and Lawton ends up apparently somewhat dead when the Prince tosses him out a window, but Cynthia takes the rap as she feels it wouldn't be nice to separate a boy from his mother. Then, Randolph shows up. And Lawton shows up...again.
