About Secret Door
Secret Door (2014–2014) is the kind of series that pays back patience — slow burns, payoffs that land, performances that feel lived-in. A re-imagining of the legendary tale of the troubled father-son relationship between King Yeongjo and his only son Prince Sado. While his father insists on a strong and centralized government, Crown Prince Sado promotes social justice and equality throughout the kingdom. Throughout eight fateful years, the strain on their relationship — both familial and political — eventually evolves into a total breakdown, ending with one of the most tragic stories in Joseon history. 1 season. 24 episodes total.
