iQiyi Unveils New Teaser Trailer for Original K-Series JIRISAN, Set To Premier On October 23rd

Teaser trailer reveals the series’ nail-biting atmosphere, as Gianna Jun and Ju Ji-hoon investigate bloody secrets hidden in the mountains

iQiyi today released the new teaser trailer for its upcoming original K-series Jirisan. Starring Gianna Jun and Ju Ji-hoon, the series was created by director Lee Eung-bok (Descendants of The Sun, Guardian: The Lonely and Great God) and writer Kim Eun-hee (Signal, Kingdom).

Jirisan follows two national park rangers – an experienced veteran (played by Gianna Jun) and a rookie (played by Ju Ji-hoon) – as they unveil secrets hidden deep in the mountains they work at. The series will see its global premiere on iQiyi on October 23rd, in a simulcast with Korea.

The teaser trailer paints a tense and mysterious atmosphere of the forest clad Jirisan mountain. The clip opens with park rangers Jun and Ju casually exploring the forest, before showing the pair frantically running around the forest as several ominous scenes flash by; including a smartphone smeared with blood stains, and a blood-covered mountaineer in a snowfield. Off-screen, a voice shouts: “We were not the only ones on the mountain! Someone murdered people!”. Overall, the trailer implies that unspeakable secrets lie within Jirisan, said to be a mountain “standing at the border of the human world and the afterlife”.

iQiyi also recently released a poster for the series, which portrays Jun walking through a forest engulfed in flames along with the tagline “Our job is to return alive from dangers”. Both the image and tagline capture the risks park rangers face in the line of duty, from natural elements such as floods and fires, in rescuing victims in the wilderness. The title font, which features a mysterious silhouette, is a further clue to the sort of secrets that lie in the mountains.

Writer Kim Eun-hee said that Jirisan was based on interviews carried out with real-life national park rangers. “When I wrote Jirisan at the beginning, it didn’t focus on rangers,” said Kim. “I was more interested in stories about mountaineers. However, I became more intrigued about their work after the interviews.”

Many amateur mountaineers often suffer injuries or become stranded because they tend to let their guard down after reaching the mountain’s peak. Rangers in contrast, believe that “the top objective of mountaineering is leaving alive”. This principle is what keeps rangers committed to rescuing victims, despite downpours, snowstorms, landslides, typhoons, and various other dangerous weather conditions. “They are really the mountain keepers,” added Kim.

Other cast members of Jirisan include Oh Jung-se (It’s Okay to not be Okay, When the Camellia Blooms), who won Best Supporting Actor at the Baeksang Arts Awards this year, Sung Dong-il (Reply 1988, The Cursed), Jo Han-chul (Vincenzo), Jun Suk-ho (Kingdom), and Go Min-si (Youth of May). From October 23 onwards, the series will be available in an exclusive simulcast with Korea on the iQiyi International app or
