In a small room filled with metal cabinets, a young brother and sister wearing animal masks are present. Wielding kitchen knives, the siblings broadcast themselves via a mobile phone camera, receiving instructions from a live chatroom. With each donation, the siblings move without guilt, like avatars in a game. A person has already been locked in a cabinet, unconscious, and the donors demand new prey. The moment the safe zone of 'anonymous perpetrators' surrealistically collapses, the genre turns into horror. One can wield king-like power or commit violence without leaving the room. This spatial attribute of the internet intertwines exquisitely with occult elements. The constantly changing camera perspectives are also worth noting. While they mostly appear to be from the perpetrator's viewpoint, fleeting moments overlapping with the victim serve as foreshadowing. Who is the person trapped?
