In a world where reality series are in high demand, an experiment was concocted: take regular folks who have dropped through the cracks in society, brainwash them to believe they are a real family, and see how they function as a family unit. The regular populace was so interested in the idea that this family was put in their own reality series, of course! Living in a closed environment and unaware of the outside world, this dysfunctional bunch do everything they can to remain sane... that is, until they accidentally escape!
A dog we like to pet on the way home from school, an eccentric guy, and ringing doorbells as a prank. That's our life in this town.
This movie depicts parallel life stories that occur in Japanese modern society. The fate is determined by a person's name in a hand-playing song, but the reality is unknown. Are they playing into the hands of someone or living invariably?
