Persécution

Daniel (Romain Duris) is a typically cool and collected guy who appears to handle things with great ease—except his girlfriend, Sonia (Charlotte Gainsbourg), with whom he shares a tumultuous, love/hate relationship. When a bizarre stranger (Jean-Hugues Anglade) begins inexplicably stalking him, Daniel's steadfast disposition gives way to growing frustration and paranoia, putting his already troubled romance with Sonia to the ultimate test.
