Plot
Kyungsoo may be blind, but his skills as an acupuncturist have earned him an opportunity to serve at the Joseon royal court, a big step up for a mere commoner. His arrival there coincides with the return of Crown Prince Sohyeon after eight years as a hostage of the powerful Qing rulers in China, whose encroachment on its peninsular neighbour are a cause for worry. The heir to the throne, in poor health, and the sightless physician take a liking to one another, but elsewhere in the corridors of the palace, whispers carry the seeds of a political crisis. Matters escalate when the prince dies under suspicious circumstances. Kyungsoo, who perceives more than others might think, is witness to this dire event, and what he now knows puts his own life at terrible risk.
