In Belle Époque Paris, the recently married Dr. Hercule Molineaux tells "one, tiny, little, hardly noticeable lie" to cover an innocent but embarrassing indiscretion. From that single untruth tumbles a cascade of increasingly convoluted deceptions, misunderstandings and mistaken identities. Compounding Molineaux's troubles are a suspicious wife, a gorgon of a mother-in-law, an outrageously aggressive female patient, her violently jealous Prussian husband, a well-intentioned friend with a serious lisp, a valet with attitude, a maid with a secret and more slamming doors than realistic architecture should ever accommodate, all adding up to a hilariously zany and infectiously charming farce.
