MC: Kang Hyeri, who used to cause trouble with her bad-mannered friends during her school days.
Her life began to fall apart when she was dragged into the murder case of one of her classmates.
With a criminal record that included fraud and violence, the only thing left to her was a loan shark debt and a shabby semi-basement room.
To pay off her debt, in the middle of the night she dared to kidnap a woman who came out of a luxurious house.
