This is one of the better and more disturbing stalker movies I've seen. Juliet Devereau (Hilary Swank) is a NYC doctor who has recently broken up with her boyfriend who had cheated on her. So she answers an ad for an apartment and the owner of the building, Max, calls her back. She takes a look at it and he immediately says she has the place, which is a little weird. Also in the building is his creepy grandfather, August (Christopher Lee), who alludes that something is up with his grandson.
As the movie progresses we realize that Max has really been stalking her and is obsessed. They become friendly at one point and make out but she realizes it's a mistake. But he wants it to continue. Then she begins waking up late for her work, feeling as if she were drugged. Well, yes, she was drugged. She installs hidden cameras in her apartment and finds out what the guy has been up to--and it's terrible.
This is a very intense, creepy character study. In a side-note, Swank and Morgan were in the romantic comedy, P.S. I LOVE YOU several years ago. Least to say, the relationship in this movie is very different.
