Raina was inherited a hotel in Semarang by her father. He and his younger brother eventually managed the hotel. However, there was one unnumbered room that his father asked him not to disturb. But now, what was in the room was starting to disturb the visitors.

After their mother’s death, Alma and Mia moved to Surabaya, where Alma became manager of Sasmaya Apartments. The 6th floor was mysteriously sealed, but an emergency forced them into unit 610. There, a ghostly woman and child warned, “Four days, sunset…” From then on, they were haunted, as anyone who enters unit 610 dies in four days at sunset.
