Set in 1990s Seoul, The Worst of Evil follows police officer Park Jun-mo (played by Ji Chang-wook), who goes undercover to infiltrate a notorious crime organisation pushing a new drug in nightclubs.
However, he discovers that his wife, Yoo Eui-jeong (The Empire’s Im Se-mi), has volunteered for the same undercover assignment, and shares history with the gang’s leader Jung Gi-cheol (played by Wi Ha-jun).
The upcoming series will also star singer BIBI, Woo Kang-min (Big Bet), Han Yi-jin (Blind) and Im Sung-jae (D.P. season two). The Worst of Evil is directed by Han Dong-wook and written by Jang Min-seok.
