When mild mannered dentist Herve Dandieu (Vidal) finds himself framed for the murder of a flirtatious dance instructor, his wife Virginie (Bardot) must find a way to clear his name. Soon she finds herself working incognito (as a dance instructor) in the seamy Parisian underworld, where nothing is as it seems. A delightful, lighthearted whodunit caper based upon a Kelley Roos novel.
