In the late Fourteenth Century, King Taejong (Kam Woo Sung) has overthrown the Goryeo Dynasty (918-1392) and taken control of what is now the kingdom of Joseon (the Korean peninsula). However, few know that his coup involved a deal with an evil spirit with the power to possess humans – and spread a wave of flesh-eating evil minions out into the world to terrorize the mortal world. Now that evil force threatens to break loose once more – and turn the kingdom into a wasteland. The king’s two sons may be all that stands in the malevolent powers’ way. The high-minded Prince Chungnyung (Jang Dong Yoon) is an ivory-tower academic, while his younger brother Prince Yangnyeong (Park Sung Hoon) has designs on inheriting his father’s throne. The terrors of the evil spirit and its cohorts spark Chungnyung into action, as he resolves to save the nation from impending doom. But his younger sibling spies an opportunity to usurp his bother – and seize power for himself... “Joseon Exorcist” is a 2021 South Korean Viki Original drama series that was directed by Shin Kyung Soo.
