Just as the head guard is about to escort Jang-Geum out. Lady Choi arrives to stop the head guard. Lady Choi reminds the head guard Jang-Geum stole the king’s record book. The head guard says she did no such thing and even if she did the matter is not for Lady Choi to be involved in. Lady Choi is pissed but leaves. Head guard tells Jang-Geum what she did was a serious matter. Jang-Geum goes back. Min Jung-Ho and Jang-Duk are worried about Jang-Geum’s safety.
The nae-ee-ohn staff is busy trying to find a treatment for the king. Lady Choi tells Geum-Young and Yuh-Ri that Jang-Geum must be trying to investigate the incident that led to Lady Han’s jailing and death. Right Prime Minister Oh goes to see the record book room guard to tell him that Jang-Geum indeed stole the king’s record book. The guard tells Oh that the matter is not for Oh to be invovled in and leaves. Choi Pan Sul’s messenger goes to see the guard next day and delivers a letter to him.
Nae-ee-ohn head doctor continues to examine the king. The lady queen asks what’s going on with the king. Lady Choi reports the royal kitchen is preparing a precious dish for the king since he hasn’t been eating well. Nae-ee-ohn head doctor whispers something in Yuh-Ri’s ears and she says she’ll follow the instructions. The medical staff are conflicted about what the king’s illness is and how they should treat him.
Jang-Geum is curious about the king’s health and asks Doctor Shin for medical books. Doctor Shin mentions a book. Jang-Geum tries to look for the book. The other nurses say Yuh-Ri is the one who’s keeping the book. Shin-Bi asks Jang-Geum why she’s always so curious about the king’s health. Jang-Geum finally tells Shin-Bi about Lady Han. Shin-Bi agrees to help Jang-Geum. Shin-Hi spies on Yuh-Ri who cooks some herb and throws away all the leftover as if detroying evidence. The other nurses comment how it’s strange that Yuh-Ri’s medicine for the king seems to change color daily.
Jang-Geum and Shin-Bi approach the medicine scholar to see what the nurses what herbs the other nurses have been using. They see nothing wrong with Yuh-Ri’s record but they continue to investigate the situation. Min Jung-Ho is investigating a treason based on a map he received which resembles the map that was stolen by a foreign woman who attacked him a long time ago. Min runs into Jang-Geum who is also rushing to investigating the Yuh-Ri matter. Shin-Bi and Jang-Geum find out the palace maids who are being treated by Yuh-Ri never received the medicines she took from the scholar.
At the town inn, Right Prime Minister Oh, Choi Pan Sul, and the record room guard meet. The inn hostess spies on the men who are talking about Jang-Geum. Min Jung-Ho gets a tip from the inn hostess, panicks and rushes back to the palace to look for jang-geum. The palace head guard meets with Lady Choi again. Lady Choi states she now has a witness on her side who speaks against Jang-Geum (the guard who met with Oh and Choi Pan Sul). The head guard has no choice but to report the incident to the lady queen. Lady Choi wants him to report to the king instead but the head guard insists he’s too ill at the moment.
The lady queen is notified that Jang-Geum read the king’s record without permission and is angry. The lady queen states the matter cannot be forgiven. Jang-Geum is captured by the guards. The head guard tells Jang-Geum there is nothing he can do. Lady Choi and Geum-Young are elated at their success.
Geum-Young presents the dish of precious meat to the king. Lady Choi praises how much trouble Geum-Young went through in front of the king. The king is pleased.
At night, Jang-Geum is covered with white cloth and taken away in secret by the guards. The Choi Pan Sul’s messenger and Young-Roh watch the event. One of the guards has a bottle of poision drink. Jang-Geum is taken to the forest and given the poisionous drink.
Back at palace, Lady Choi tells Geum-Young that Jang-Geum has fianlly met her end. Just as they’re about to celebrate their success, guards arrive at their door. The guards state the king has fallen unconscious from eating the food prepared by Geum-Young, thus Geum-Young is taken away by the guards for further investigation and questionning. During the questionning meeting the head doctor turns his back on Lady Choi and Geum-Young by suggesting that something must have gone wrong with Geum Young’s cooking and a similar incident has occured before. Lady Choi is shocked by the head doctor’s behavior and tries to defend Geum-Yuong but at last Geum-Young is held captive until further investigation.
Doctor Shin and Doctor Jung agree that the culprit must not be food as Jang-Geum has suggested.
The nurses wonder where Jang-Geum is since she’s been missing for a day. Yun-Saeng finds out Geum-Young is captured from Lady Min and Chan-Ee. Shin-Bi arrives at Yun-Saeng’s looking for Jang-Geum. Not finding her there, Shin-Bi goes to look for her with Jang-Duk. Jang-Duk is out of town but a man tells Shin-Bi that Jang-Geum hasn’t returned since she went back to palace.
Kang Duk Gu and wife find out about Geum-Young and start dancing. Shin-Bi arrives then to look for Jang-Geum.
Jang-Geum is covered with white sheet and brought to a room. The guards remove her mask and in comes the lady queen. The lady queen tells Jang-Geum she set up Jang-Geum’s fake death because the lady queen believes Jang-Geum can clear up the king’s real health concern. The lady queen tells Jang-Geum must uncover the conspiracy if she wants to return to the palace, or else she will disappear forever.
