Season 1

Bad Guys (나쁜 녀석들, 2014), Season 1 is a Korean crime-action drama you can watch online on iFILM — eleven episodes in which a police chief decides the only way to catch monsters is to recruit a few of his own.

Suspended detective Oh Goo Tak gets a free hand: build a unit out of convicts and aim it at Seoul's most dangerous criminals. The roster is brutal — heavyweight gangster Park Woong Chul, contract killer Jung Tae Soo who turned himself in, and Lee Jung Moon, a teenage genius with a 165 IQ and no memory of the murders he committed. Inspector Yoo Mi Young is assigned to keep the pack in line, convinced men like this can never work together. The bait is simple: whoever cracks the case first shaves time off his sentence. Raid after raid, the team's predatory logic begins to fray, and which of them is truly the "bad guy" stays an open question.

This OCN series runs on the chemistry of its four leads and some bone-crunching fights, with Ma Dong-seok's Park Woong Chul still quoted today. It's less a procedural about honest cops than a grim story about monsters on a short leash. Stream Bad Guys Season 1 online on iFILM.
