Juliet Devereau, an emergency room physician, rents an apartment in New York City from Max. Juliet has recently filed for divorce from her husband Jack after she caught him having an affair, but she still has feelings for him. Unbeknownst to Juliet, someone is stalking her, observing her from across the street and apparently entering her apartment.
At a party, Juliet bumps into Max and flirts with him. As they walk home, Jack follows them from across the street. Juliet impulsively and awkwardly kisses Max, but then retreats after realizing she shouldn't have done it. They later go on a date. A flashback reveals that Max is the one stalking Juliet. He has rebuilt her apartment to include secret passageways and a two-way mirror, which he can use to watch her.
In another instance, Juliet and Max are in bed together and are about to have sex. However, Juliet feels guilty and asks Max to stop, admitting that she couldn't stop thinking about Jack. Eventually Juliet breaks off her romantic relationship with Max, saying that her kissing him and them almost having sex was a mistake and she was too caught up in her emotions to realize what she was doing because of her feelings for Jack. Max continues to observe Juliet and does strange activities in Juliet's apartment while she's at work (such as masturbating in her bathtub and brushing his teeth using Juliet's toothbrush). He also watches her and Jack have sex. Afterwards, he begins drugging Juliet's wine so he can be closer to her while she is unconscious. After oversleeping for the third time in two weeks, Juliet becomes suspicious that she may have been drugged and has security cameras installed in her apartment.
After a date with Juliet, Jack is attacked and injured by Max. That night, Max drugs Juliet and attempts to rape her while she sleeps, but she awakens and he flees after giving her an injection. The next morning, Juliet finds the cap from the hypodermic needle. At work, she has her blood and urine analyzed and discovers high levels of Demerol and other drugs in her system. She rushes back home and finds Jack's possessions there but no sign of him. A nightshirt of hers is in a location where she did not leave it. She checks the security camera footage and sees Max assaulting her.
Max enters her apartment and tries to get her to drink some wine, but she refuses. He then assaults her, stabbing her with a hypodermic. She gets away and locks herself in the bathroom, but Max breaks in through the bathroom mirror and pulls her into one of the secret passageways. During the process of trying to hide from Max, she finds the corpse of Jack, who has been murdered by Max. The realization provokes Juliet to fight back against Max, and she quickly gains the upper hand, shooting him multiple times with a nail gun before killing Max by shooting him in the head, before escaping.
