Despite her beauty, Eun-jin is a feared and respected fighter who dominates the male-centered underworld. When she finds out her long-lost sister is dying of cancer and that her last wish is to see her married and ‘taken care of,’ she sets out to get married. Eun-jin’s henchmen discover Su-il, a shy and lonely civil servant, naïve enough to marry her. He has no idea that his bride is a gangster, and wakes up from his dream of blissful newlywed life to one of constant household chores and a wife who refuses to sleep with him. Eun-jin, on the other hand, has to spend most of her time defending her gang from rivals who want her eliminated. To make matters worse, Eun-jin’s sister asks Eun-jin to have a child with Su-il for her. There is nothing Eun-jin will not do for her sister. But, Su-il begins to suspect that his wife has a dark secret life. He decides that enough is enough and he wants a divorce. That same night, however, Eun-jin’s top rival gang, “White Shark,” makes their move to take over. A battle takes place and Eun-jin is seriously injured. Su-il visits Eun-jin at the hospital and he realizes that he is still in love with her and we learn that he may not be as meek as he appears.
