58-year-old Gentaro Ito lives with his wife Chizuru in a house in Tokyo. Each of their three daughters should have left home and lived well. However, their eldest daughter, 28-year-old Yuka, is single and doing well at work but has a propensity for affairs. Their 25-year-old second daughter, Rika, wedded a highly educated man and lives in Osaka but the couple are on the brink of divorce. Their youngest daughter, 22-year-old Mika, is also single, and the moment she gets to start living on her own, she half-cohabits with a man who does not seem like he will be a successful manga artist. Gentaro worries endlessly about his daughters who are poor judges of character. Completely ignoring their tastes, this stubborn, old-fashioned father suddenly brings a man whom he likes to the house in the middle of the night and introduces him to his daughters. In fact, this man is Yuka's ex-boyfriend. What will the family be like the next day!?
