Synopsis
Jirisan (2021) is a Korean detective drama series you can watch online on iFILM. Director Lee Eung-bok set the story inside one of South Korea's most remote national parks — a mountain range where the terrain itself becomes a character. The show stars Jeon Ji-hyun and Ju Ji-hoon as two rangers whose partnership turns into something far more complicated than rescue work.
Seo Yi-gang has spent years learning every trail, every weather pattern, every blind corner of Jirisan. Kang Hyun-jo is newly posted — a former military officer, physically capable but still reading the mountain. When hikers start dying in ways the terrain alone can't explain, the two begin piecing together a pattern the park has hidden for a long time. Each rescue mission pulls them deeper into something neither expected.
The series earns its tension slowly. It's a procedural on the surface — operations, dispatches, emergency gear — but the mystery underneath keeps tightening. Viewers who prefer Korean dramas that build atmosphere rather than rush to payoff will find Jirisan rewarding. Stream the full series online on iFILM.
