Jirisan — Season 1
Jirisan National Park holds no secrets from Seo Yigang – she’s its most skilled ranger, intimately familiar with every peak and path. Joining her is Kang Hyeonjo, a fresh-faced rookie who brings an unexpected background; a former army captain and military academy graduate carrying a deeply personal burden he can't share. Thrown together as partners, they navigate the challenging terrain of Jirisan, dedicating themselves to rescuing those who find themselves in peril within its vast wilderness.

Ranger Kang Hyeonjo, recently assigned to the park, found himself tasked with a search: a missing teenager somewhere within the sprawling wilderness of Jirisan National Park. His efforts, however, were complicated by the arrival of a typhoo…

High on the mountain, pursuing a personal vision, Hyeonjo encounters a man seeking his father's remains. Drawn together by this shared, unspoken purpose, they proceed their perilous climb as companions.

The rangers interrupted a shamanic ceremony, and as they did, a girl discreetly passed a cryptic message to Hyeonjo. Shortly thereafter, the team received a report: an elderly woman had vanished.

In a video recording, Seo Yigang witnesses a disturbing spectacle. It was in 2018 that his team was unjustly held responsible for the death of a villager.

Yigang informs Hyeonjo that she observed an individual with lacerations on their hand, a detail that fuels her suspicion they might be connected to the bombing. Meanwhile, the rangers initiate a search for Lee Yangseon.

A blanket of snow silenced the park, muffling sound and blurring the edges of the world. Yigang received word that a man bearing the same name as her first love was due to retrieve a forgotten object. A vehicle, unremarkable yet unsettling …

Yigang senses that Hyeonjo's spirit drifts among the peaks. In the year 2019, Hyeonjo experiences a vision of flames. Though separated by distance, both men face peril.

The aftermath of the rescue brought a chilling revelation: someone had been systematically attempting his demise. A grim certainty settled upon Hyeonjo – the recent string of murders were not isolated incidents, but connected to a plot aime…

Lee Dawon is gone. Rangers venture into the wilderness to find him, and discover his phone. Within its memory lies a troubling voice recording, featuring a person Dawon wouldn't expect to hear.

A man lay in the road, seemingly stunned. Elsewhere, Yigang and Hyeonjo, lost on their path to a village, observed unsettling lights flickering in the distance.

The arrest of Cho Daejin, implicated in Dawon's death, cast a long shadow. Meanwhile, Yigang found himself increasingly convinced that the perpetrator lurked within the ranks of the rangers themselves.

Torrential rain has confined climbers within the park, prompting a search by the rangers for stranded groups. Amidst the difficult conditions, Yigang encounters a survivor of the devastating 1995 flood, a woman who lost her parents in the d…

The downpour brought death. Hyeonjo learned the bridge collapse was no accident, and began to trace the links between those who perished.

In the quiet village of Geomeundarigol, Hyeonjo apprehended a man clad in black gloves, his presence immediately unsettling. Following the man's account, a seed of doubt took root within Hyeonjo, leading him to consider the possibility of a…

The decision to disconnect Hyeonjo from life support was made by his family. Meanwhile, the rangers began their inquiries into those with ties to the village, and Yigang experienced a sudden, profound understanding.

Once the truth was brought to light, Yigang interrogated the offender with relentless intensity. The guilty party attempted to hide incriminating evidence, but there, they encountered Hyeonjo's spirit.
