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!

Fed up of being mocked by the rest of his family because he can't see ghosts, Osamu decides he'll impress them by summoning a UFO. However, when his plan actually works and a UFO does appear, he keeps it a secret and starts behaving very oddly indeed. Why is Osamu working late all the time now? Why does he have lots of new female friends and why are the 'men in black' so interested in him?
