27-year-old Akiha Ōkado, who vows to stay single, gets a proposal to enter into a fake marriage from 30-year-old Shū Momose, who wants to get the status of a married man for some reason. Through living together as a fake couple, their relationship gradually changes.

After participating to a previous show where they have to bet or be challenged to any kind of competitions, the losing members of the Gaki no Tsukai are selected to spend 24 hours in a setting which they have no knowledge of the theme nor the course of the events. They are exposed to various absurd and crazy situations nonstop for 24 hours and must refrain from laughing. If they do so, hang-men appear and hit the rule breakers with a weapon (the weapon varies every year).
