Who does not want to finally see a movie about the Japanese female bomb makers out there? Mikiko (Koizumi, Kyoko) disappeared a long time ago and is considered dead by her family, that is until she walks in through the door and uncomfortably settles back in. Her niece Kako (Nikaido, Fumi) is there and has been bored for some time. Still, she does not necessarily want her aunt as a room-mate. Then there is the rest of the family. They are not so ordinary either.
