When an old building collapses resulting in several casualties, a disaster medical support team is dispatched to the site.

Doldam Hospital receives news of a second collapse, but the place is still full of injured people. Teacher Kim leaves everything and heads to the scene.

Go Gyeong-suk does not give up the legal battle over her son's death. She proposes a secret deal to bring down Jin-man, but Teacher Kim opposes to it.

A fire approaches as if it would devour Doldam Hospital at any moment. Only after evacuating all the patients do the staff realise Teacher Kim was gone.
