Maika Monroeas Julia, a young American woman who has moved to Romania for her husband's new job, is obsessed with a strange guy, the nameless Watcher (Burn Gorman), who appears from the apartment across the street. Okunos' feature film is based on a fairly basic, classic thriller narrative.
Julia suffers from an intense sense of loneliness as she spends her days alone, listening to Romanian language lessons as she explores the city. When Francis invites his colleagues over for dinner, they openly converse in Romanian, making Julia feel patronized as a child at the adults table. They explain the disturbing, gory details with desensitized intrigue.
Benjamin Kirk Nielsen, the director of photography, often films Monroe in her apartment through the window, increasing her uneasy feeling that someone is watching her. She is reportedly adamant about looking past her, but this time, she notices a man walking past her from the movies to the grocery store. This creates a haunting, menacing atmosphere and creates a subtle doubt in our minds.
Julia's husband, who continues to dismiss her worries, minimizes her worries and treats them as inconvenience. A police officer goes to the same location where she lives, and she crumbles, desperately pleading with him to believe her.
Julia's apprehension comes to an end when she attends a fancy work event with Francis. Her eyes begin to change as she attempts to grasp the meaning of what her husband is saying. She quickly walks out of the party, but not before Francis confronts her, threatening to leave her. In a striking wide shot, Julia stands alone in the grand lobby of a luxury hotel, with the rest of the party continuing to mingle on the floor above her.
Julia is left alone at the dark train station when she notices the Watcher standing nearby, shifting from warm to threatening. His tone switches from warm to threatening as the frame slowly zooms in on his grocery bag. It's a terrifying and satisfying confirmation that Julia's paranoia was real.
Julia finds Irinas headless body in her apartment. The Watcher then attacks her and pretends she killed him, only for her to use him to shoot him to death in the final shot. He has been the subject of his deadly gaze throughout the film, but now, she gets the powerful and cathartic last glance. She finally takes action and receives the sweet, blood-soaked revenge she deserves.
