Agatha Christie's mystery masterpiece gets a delectable French update in this smart, sharply acted whodunit. The aristocratic governess Camilla, played by Danielle Darrieux, has her quietly luxurious routine interrupted when several guests drop in - amongthem, her nephew Guillaume, played by Melvil Poupaud, his saucy new wife - the gorgeous Laura Smet - and Guillaume's ex-wife, played by Chiara Mastroianni. Things take a murderous turn when Darrieux is found dead in a double homicide. Luckily, InspectorBataille - a delightful Franois Morel - arrives to solve the case and, in the process, uncovers jealousies and conspiracies amidst a web of nasty family secrets.
