The effects are catastrophic when a 6.5 magnitude earthquake hits Seoul. Buildings collapse, roads are blocked, rations and medical help are needed and people are more than desperate to save what's left of their lives.
In the midst of this natural disaster, two people continuously clash in a battle of moral values: Lee Hae Seong, a trauma surgeon at Mirae Hospital, and the director of said establishment, Park Geon.
Lee Hae Seong values every life and wants to save as many as possible, while Director Park wants to close down the hospital to save his reputation and prevent being sued in case something goes wrong with a patient.
Soon, Hae Seong finds himself pushed to his limits while he tries to manoeuvre between selfish higher ups, greedy politicians, the lives of his patients and the consequences of the disaster.
