To prove the extreme power of the ice stone, Jin Ho Gyeong (Park Eun Hye) kills Mu Deok (Jung So Min), and tries to bring her back to life.

However, she senses a familiar feeling when she hears Mu Deok call her mother. All of the semblance she shares with her long lost daughter.

When So Yi (Seo Hye Won) realizes what's happening, she destroys the ice stone. Because of this, the powerful ice stone traps them inside a powerful barrier with no way out.

Outside of the barrier, Park Jin (Yoo Jun Sang) and Jin Mu's (Jo Jae Yoon) suspicions about the true identity of Mu Deok grows.

Little do they know, the soul shifter who remains alive is hiding inside the premises, and has made a deal with So Yi to lure Seo Yul for him to kill.
