Late at night or during holidays, the terror that befalls women who forget their access cards in an empty office. Security systems introduced for crime prevention can ironically create dangerous situations. Even companies with on-site security guards cannot guarantee safety, as the presence of a guard does not always mean protection.

Experience the eerie, anxiety-inducing events unfolding between the guard's twisted sense of justice and cruelty. Immerse yourself in the dark presence lurking in tonight's office.
