Movies like The Garden of Sinners: Overlooking View (2007)

The story starts following an incident: a young girl jumps from the top of a building. The image provokes a certain dread, as the girl appears to have been a corpse even before she jumped. The case is dismissed, yet more and more of these suicides occur, and all from the same building. Thus began the rumour, that a ghost inhabited the rooftop of the building.
