The Imawano family move into their new home and soon discover that it's no ordinary house. The whole family start to see and hear strange things, especially Kiyoshi. What is behind the door that won't open? Why is Kiyoshi the only one who can see ghosts and can he really save the family from the crisis that his dead Grandfather has warned him about?

Kiyoshi is coming to terms with his new psychic abilities and seems to have a new room-mate, the ghost Asami.

The rest of the family discuss their various spooky encounters but conclude that there's nothing supernatural going on. Meanwhile Osamu, who has no psychic abilities whatsoever, comes up with a plan to persuade the rest of the skeptical family that the house really is haunted.

The house has also attracted a wandering priest who tries desperately to warn the occupants of their dire situation.

When Kaoruko (an old friend of Grandmother Kiwa) comes to visit, Kiyoshi immediately suspects that she's far from being the frail old lady she appears to be. With the rest of the family already under the old hag's spell, can Kiyoshi, with the help of an apparition detector and his temporarily disembodied father, save them all?

Osamu causes more problems for the family when he discovers a peculiar antiques shop (with an equally peculiar owner) and brings home two items - a cursed portrait that likes a good laugh and a severed arm desperate to find the rest of its body!

Inspired by a TV show they saw, the family have a light-hearted discussion about remodelling the house. When a ghostly engineer arrives the following morning to survey the house, the house becomes a bizarre maze of rooms that seem impossible to escape from.

The Men in Black, with the help of Osamu, continue to investigate spatial anomolies. Meanwhile, Kiyoshi starts to see visions telling him that he will die in 4 days! Fortunately help arrives in the form of the priest Kyuujuurou, younger brother of Hachikuro. He tells Kiyoshi that the explanation for all the recent strange phenomena can be found in ancient scriptures stored in the mysterious 'room that will not open'.
