This is a rather complex thriller that fails to deliver very much suspense or fear, in spite of the requisite shock scenes and mystery over who is perpetrating them. The story opens with a pending marriage, tragically aborted when the groom dies under suspicious circumstances, and continues several years later when Nathalie (Carole Laure), a single mother, receives "breather" phone calls and finds the bloody heart of an animal on her car seat. That is followed by another such donation sent to her workplace and labeled as the heart of her little daughter. Although gruesome, these incidents alone are not enough to create an atmosphere of foreboding, anxiety, or apprehension -- as Nathalie seems just a few steps from unconcerned. If she is not affected, any tension created by the scenario is diffused, leaving the audience in neutral. ~ Eleanor Mannikka, Rovi
