As the chic and serious professional begins to pull at threads of intrigue, the film becomes an enjoyable genre-blending psycho-drama reminiscent of 1990s classics.

Fans of Jodie Foster will already be aware of her language skills - she attended a French school in Los Angeles and spoke the language from a young age. But few will have seen her perform in French, and here she, and a fantastically watchable supporting cast of Daniel Auteuil and Matheiu Amalric, play middle-class, middle-aged Parisians with murder on their minds as a mystery unfolds.

Festival regulars will recognise Park Ji-min, who starred in the award-winning, Return to Seoul, as Steiner’s daughter-in-law.
