|Eun-jin is a living legend among the gangsters. She dominates the male-centered underworld wielding only a pair of her trademark blades. One day, Eun-jin finds her sister from whom she was separated at an orphanage during childhood. Her sister, not knowing of her dark life, tells Eun-jin that her last dying wish is to see that she gets married. Su-il, an ordinary civil servant, is a lonely homebody who failed 58 times in dating. One day, Eun-jin's henchmen discover him and realize that he would be the perfect candidate for a husband. He appears to be the only man naive enough to be dominated by Eun-jin, and the two are married. After the wedding, Su-il learns that what is waiting for him is a life of constant household chores and a bride who refuses to sleep with him instead of a blissful honeymoon. Eun-jin, on the other hand, is finding the life of the leader of gang more demanding than ever before. 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.
