A young American woman (Kristen Stewart) works in Paris as a personal shopper for a diva like socialite celebrity (Nora Von Waldstatten). She is also trying to communicate with her recently deceased brother since they shared an ability to communicate with the dead. When she starts to receive a series of mysterious texts on her phone, it will lead her further into the darkness. Stewart and director Olivier Assayas (who won the Cannes film festival award for best director for this film) had previously collaborated on CLOUDS OF SILS MARIA and the teaming proved a rewarding artistic collaboration for both and the quality of both their work is continued here. It's a difficult film to categorize. While it has elements of the supernatural and an intriguing mystery at its core, I'm hesitant to refer to it as a horror film or a thriller. It took awhile for the film to find its rhythm but when it did I was totally hooked. It's both elegant and unsettling in its fluctuations while remaining disturbing through out right up until its ambiguous ending. Stewart turns in a terrific performance. She gives us just enough to decipher the potential complexities that even her character may not be aware of. With Lars Eidinger, Sigrid Bouaziz and Anders Danielsen.
