Through the Darkness (Season 1)

Through the Darkness (2022) is a Korean crime thriller you can watch online on iFILM. In the late 1990s a string of motiveless killings rattles the country, and a police force used to beating out confessions has no idea who is doing it or why. Quiet analyst Song Ha-young takes on something nobody there has tried: getting inside a killer's head.

In doing so he becomes the first criminal profiler in the South Korean police. Ha-young and his team pick apart suspects' behavior for hours, butt heads with superiors who treat the whole idea as a waste of time, and track murderers who leave almost nothing behind. Kim Nam-gil leads, with Kim So-jin and Jin Seon-kyu alongside him.

The script grew out of the memoir of a real man, one of the country's earliest profilers, so patience and method matter more than chases or shootouts. The tone stays cold and measured, with no cheap scares: it cares more about how a murderer's mind works than about blood on screen. A strong pick for fans of slow-burn procedurals in the vein of Mindhunter. Stream Through the Darkness (2022) online on iFILM.
