Shane, an American doctor who travels to Paris to seek his former paramour Coré. The mysterious Coré escapes her husband's domestic confinement every day to find sex with strangers, and she ends each encounter by murdering them. Shane feels an irresistible urge to reunite with her despite the danger ahead.

The biggest shock in this unconventional vampire film is not the gore, but rather Denis’s ability to dive into the visceral nature of the characters’ desire to connect and destroy.
