The Tale of Nokdu

Nok-Du, who is living on a small island, witnesses his father and brother get attacked by a group of assassins. He decides to leave home and find out who they are and work for. He follows the leads and arrives in Hanyang.

Nok-Du disguises as a woman and enters the village where only widows are allowed to live. Fortunately, no one is suspicious of Nok-Du yet. He finds out that there's a gisaeng house right next to the widow village.

At night, Nok-Du happens to overhear the conversation of a group of widows who look like trained assassins. Nok-Du starts to follow one of them into the woods. Meanwhile, Nok-Du's father and brother move from the island to the mainland. Yun-Jeo, Nok-Du's father, decides to go to Hanyang to take care of unfinished business.

Nok-Du and Dong-Ju become close. Nok-Du helps out Dong-Ju when she is having a hard time because of her injured hands. Dong-Ju says that she wants to treat Nok-Du like an older sister. Nok-Du happens to see a shaman and widows performing a religious ceremony, and he thinks that the widows are scheming something.

Dong-Ju realizes that Nok-Du has been pretending to be Lady Kim so far. Nok-Du persuades Dong-Ju to let him stay in the village. The widows talk about a man who sneaked into the village last night, and they plan to catch him by making a composite sketch of him. Nok-Du decides to give the widows misleading information about the man to confuse them.

Dong-Ju hears a rumor about the man who broke into the village the other day. She realizes that it is not a good idea to let Nok-Du stay in the village. She asks Nok-Du to leave the village. Meanwhile, Nok-Du finds out that a group of widows is planning to kill someone, and he makes a deal with the widows.

Nok-Du decides to help Dong-Ju so she doesn't have to be a gisaeng. Nok-Du gives up the mission that the widows of Muweol Corps gave him. He goes to meet Lady Cheon with an idea that can help Dong-Joo. Meanwhile, the widows of Muweol Corps agree to give Nok-Du the second chance and order him to complete another mission.

Dong-Ju keeps being reminded of her childhood and family after she came to Hanyang. She visits the house she used to live when she was a child. That's when she runs into Yul-Mu. And Nok-Du happens to watch them have a chat from afar. Nok-Du manages to complete his mission, but he hears that the real Lady Kim and her servant got caught.

Nok-Du returns to the village for widows with Dong-Ju and Yul-Mu after completing his mission in Hanyang. However, the widows and gisaengs in the village think that Nok-Du likes Yul-Mu. Meanwhile, Yun-Jeo and Hwang-Tae see that a group of assassins are in front of their place. They start to run away from the assassins.

Nok-Du is curious about who Dong-Ju likes. He asks her who it is, but she never tells him. Nok-Du decides to tell Dong-Ju his feelings for her, but Dong-Ju tries to keep her distance from Nok-Du.

Yul-Mu finds out that Nok-Du has been pretending to be a woman all this time and that Dong-Ju has been looking out for Nok-Du. Yul-Mu wants to know if Dong-Ju has feelings for Nok-Du. And Nok-Du tells Dong-Ju that he will make her fall in love with him.

After the widows of Muweol Corps left for Hanyang to kill the local functionary, Nok-Du and Lady Cheon find out that the widows are in a trap. Lady Cheon asks Nok-Du to go help out the widows, and that's how Nok-Du becomes a member of Muweol Corps.
