When a potent new recreational drug begins spreading throughout Seoul’s liveliest venues, an undercover officer will infiltrate the gang responsible in The Worst of Evil – a thrilling new crime drama coming September 27, exclusively on Disney+.

In 1990s Seoul, a former DJ seizes control of a gang and begins pushing a popular new drug nicknamed “Gangnam Crystal” in the city’s nightclubs. With little known about its source, a rural officer is recruited into an undercover police unit and is tasked with infiltrating the gang to bring it down from the inside. Forced to keep his new assignment a secret from everyone, officer Park Junmo is stunned to discover his wife and fellow officer Yu Euijeong has volunteered for the same assignment and that she has a mysterious past with the city’s new drug lord. Torn between his dedication to his job and his need to keep his wife safe, Junmo’s actions will keep viewers on the edge of their seat throughout.

Starring Ji Changwook (Backstreet Rookie, Suspicious Partner, Empress Ki) as police officer Park Junmo, Wi Hajun (Squid Game, 18 Again, Little Women) as DJ turned gang-leader, Jung Gicheul; and Lim Semi (My Secret Terrius, Shopping King Louis) as security officer Yu Euijeong, The Worst of Evil is directed by Han Dongwook (Man in Love) and written by Jang Minseok (Secret Union, Maundy Thursday).
