A photojournalist is confined to his apartment after suffering an accident that leaves him unable to move. While he recovers from his injury, he finds himself trapped in a monotonous routine, and to pass the time, he begins to observe his neighbors through his window. What starts as innocent curiosity soon transforms into an obsession when, while watching an seemingly normal man in the building across the street, he realizes that something doesn’t quite fit in that man’s life.
Each day, the photographer takes note of the strange interactions and behaviors of this neighbor, who is not only an enigma but also appears to have a dark secret. The plot thickens when the protagonist begins to suspect that the neighbor might be involved in a horrible crime. With the help of his girlfriend, who is increasingly worried about his mental state, he tries to gather evidence and uncover the truth behind the seemingly calm facade of the neighborhood.
As his investigations bring him closer to the revelation, it becomes a dangerous game; he not only risks his own safety but also challenges the limits of privacy. His quiet life spirals into paranoia and tension, pushing him to the brink of insanity, as the mystery intertwines with his own existence, blurring the lines between the observer and the observed.
