Knight Flower

As a widow, Yeo-hwa cannot leave her home and has to mourn her late husband day and night; she often sneaks out at night and helps people in trouble by disguising herself as a man behind a black mask.

Yeo Hwa decides to save Kknot Nim by herself; the Minister of Finance summons Soo Ho, as a masked man sneaks into his house and steals his precious painting.

Soo Ho realizes Kang Pil Jik of Pil Merchant Guild is also searching for the painting that Yeo Hwa stole; Soo Ho leaves a note to the masked hero at Myungdo Inn to give a warning; Yeo Hwa attends a relief with her mother-in-law.

Soo Ho visits Myungdo Inn to get the painting fixed and runs into the masked hero; she lets him know that Pil Jik has been kidnapping children from shantytown; the King and Yoon Hak look for the members of the late King's guards.

Yeo Hwa and Soo Ho find where Pil Jik hides the kidnapped children in Pil Inn; they manage to rescue them but are at odds about where to take the children; the Minister of Finance passes away and his servant gets arrested as a suspect for murder.

Aware of Yeo Hwa's true identity, Soo Ho takes measures to prevent her from engaging in any reckless behavior; Yoon Hak and Lee So discover that Sung Hoo is the King's Guard who vanished after receiving a secret order from the previous king.
