The Intruder (1999)

Synopsis

Catherine moves to a new city, and Nick Girard, a composer of film scores, catches her eye. They marry, but almost instantly something seems amiss. Nick had a previous wife named Stella, but she was killed two years earlier and her presence seems to still reside in the apartment. The neighbours in the building aren't exactly welcoming, either. Catherine begins to think that an unseen force is trying to warn her about Nick, who starts to doubt her sanity.
