Mobile Police Patlabor 27 - "A Calling Voice in the Dark"

Division 2 are out on a training mission at a group of abandoned buildings set for demolition. They are training for urban combat and hostage situations. Everything seems to be going fine until the nightshift comes. Local residents claim that the buildings are haunted. Voices can be heard at night and a ghostly group of samurai can sometime be seen. Shinshi discovers that disaster and death have always befell the area, with many deaths due to earthquakes, especially the big one which happened four years prior. One night Captain Goto's computer malfunctions and the word "Help!" scrolls across his screen continually. Then he is attacked by a man with a sword who vanishes! Later, Ohta feels someone "tugging" at his Labor and Noa sees a ghostly vision of a young boy. Are these mysterious occurrences the work of spirits? Is the site cursed?
