Overview
The Throne is a 2015 South Korean historical drama film directed by Lee Joon-ik, starring Song Kang-ho and Yoo Ah-in. Set during the reign of King Yeongjo, the film is about the life of Crown Prince Sado, the heir to the throne who was deemed unfit to rule and, at age 27, was condemned to death by his own father by being locked in a rice chest for eight days.
The Throne won three awards at the 35th Korean Association of Film Critics Awards, including Best Film. It was also selected as the South Korean entry for the Best Foreign Language Film at the 88th Academy Awards, but it was not nominated.
Plot
The film opens with the crown prince, Sado, carrying out a plot to kill his father, the king. However, the assassination - for untold reasons - does not take place.
The next day, Sado's mother goes to the king to encourage him not to punish Sado's son when he punishes Sado. The king summons Sado and tells him to kill himself. Fearing for their own lives, Sado's supporters rush in and save him from suicide. Instead the king orders Sado into a large rice box, which he then nails shut since no one else will do it for him.
