Set on a fictional, medieval-inspired Joseon, Kingdom explores the story of a Crown Prince, as he sets to investigate the source of a mysterious plague that begins to ravage his country. It stars Ju Ji-hoon, Ryu Seung-ryong, Bae Doo-na, Kim Sang-ho, Kim Sung-kyu and Kim Hye-jun.
Set during Korea’s Joseon Dynasty, three years after the Imjin War, the first season of Kingdom follows the story of Crown Prince Lee Chang (Ju Ji-hoon) and his subordinates, who stumble across an unnatural plague that resurrects the dead amidst his investigation of a brewing political conspiracy and rumors of the King of Joseon’s death. Amidst the chaos and death that ensues, Chang meets allies who try to make a stand in the city-state of Sangju before it spreads further into the province, only to discover that the plague has already adapted. The second season picks up during Lee Chang’s struggle to save his people from the spread of the plague and his dynasty from the machinations of the powerful Haewon Cho clan who hides a sinister secret.
