Before my 30th birthday, my beloved husband gave me a ticket to a luxury hotel. And on that day, "PM 3:00", which was the climax of happiness. A group of three young men wearing suspicious masks arrive at the hotel room where they checked in with their husbands. In fact, the husband who had a large amount of debt secretly Kanna had made a contract to present his beloved wife as collateral. 20 hours until check-out, a change in the back of Kanna's throat who has been raped by young people has come.
