Secret Door

A re-imagining of the legendary tale of the troubled father-son relationship between King Yeongjo and his only son Prince Sado.

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.
