Hiroyuki Kitahara was leading a rather ordinary life in a quiet Japanese town, and decided one day to take a stroll at night, enjoying the picturesque landscape. All of a sudden, a horrifying monster appeared right in front of him. Kitahara wakes up in the hospital and tries to convince the doctors that he was not hallucinating. Teaming up with a young female journalist, Kitahara begins to explore the city, searching for clues to solve the mystery and seeking meeting with onryou - ghosts of people who were wronged in their lifetime and who are back for revenge.
