The story of the woman that would become Empress Ki, and her struggles as she worked her way through war, political conspiracies, and the imperial palace to become Empress of China. This Korean Drama re-imagines the historical figure as a fierce, independent woman who goes to extreme lengths to protect those she loves.

Soo-myung and Seung-min, both 25 years old, meet for the first time at Soori Hope Hospital, a run-down psychiatric facility located on a mountain. Soo-myung has been institutionalized since he was nineteen after the trauma caused by his mother’s suicide, and has a phobia of scissors. Seung-min is sane and a champion paraglider, but was forcibly committed by his greedy half-brother to get Seung-min’s share of the family inheritance. Soo-myung is a model patient, peacefully and passively spending his days in the hospital despite its abusive nurses, unlike Seung-min, who is a walking time bomb. Soon, Soo-myung gets roped into Seung-min’s reckless plan to break out of the hospital.
