Bi Dam tells Queen Seon Deok that Yu Shin is involved in the restoration movement. She believes in him and approves the investigation of Yu Shin. Yu Shin tries to persuade Wol Ya to confess to Queen Seon Deok their real intentions. But Bi Dam deliberately hinders.

Yu Shin is found by Bo Jong within Baekje's territory. Bi Dam orders that Yu Shin be captured. While the officials are discussing whether Yu Shin is a spy, Seon Deok confirms that Yushin had gone to Baekje as a spy under her order. Yu Shin comes back to inform the court that there are spies in Daeya Fortress and that it will be attacked. However, Bi Dam and the rest do not believe in him. While Seon Deok is in dilemma, Bi Dam proposes a royal nuptial between them and that he will surely help her to save Yu Shin. While everyone thinks that Yu Shin has given a wrong information, Daeya Fortress is captured by assault.
