Plot

Daisy Rain goes to her apartment in the Lusman Arms, a former luxury hotel undergoing renovations, and is beaten to death with a hammer by a man wearing a balaclava. In another room, new tenants Nell and Steven Barrows, a teacher and a medical intern, are introduced to the amenities and a few of the residents by Byron, the building manager. As Steven works long hours, Nell is left alone most of the time, and befriends Julia Cunningham, a neighbor down the hall, and Chas Rooker, an elderly man who reveals some of the history of the structure, mentioning it was made by Jack Lusman, who disappeared mysteriously, and that builders died while working on it.

As days pass, the Lusman Arms are plagued by mysterious circumstance; strange noises are heard throughout it and coming from the intercoms, Nell finds a trinket containing human teeth in a wall, and Julia and another tenant vanish, having been killed (with a drill and a nail gun, respectively) by the ski masked murderer, who hides their bodies. While looking into Julia's disappearance, Nell speaks with Chas, who offers cryptic warnings about the nature of the building, and sneaks Nell a note reading "Look for her in Room 504". Nell takes the advice, and discovers that there is no Room 504, and that all the other floors lack apartments whose numbering should end with 4.
