iQiyi original Korean drama Jirisan, created by director Lee Eung-bok (Goblin, Descendants Of The Sun), writer Kim Eun-hee (Kingdom, Signal) and starring Gianna Jun and Ju Ji-hoon, confirms its global premiere in October on iQiyi international, simulcast with Korea.

The highly anticipated K-suspense series was shot in Korea’s highest mountain of the namesake and released a sneak peek on September 14. In the video, Jun plays a fearless national park ranger that puts on a full set of professional mountain climbing gear and treks alone against the threats and tests posed by mother nature with no signs of distress. Jun perseveres to rescue people in need. The mysterious ambiance in the stormy forest implies an unknown future and unspeakable secrets ahead.

After 10 months of shooting, Jirisan marks Gianna Jun’s first suspense drama and her return to the small screen after five years since Legend of the Blue Sea. She will unveil mysteries in Jirisan together with Ju Ji-hoon, Sung Dong-il and Oh Jung-se, while introducing the rarely seen life of forest rangers.

iQiyi original K-series Jirisan tells a story of how an experienced national park ranger (played by Gianna Jun) and a rookie ranger (played by Ju Ji-hoon) unveil secrets hidden in the mountain. The show will exclusively simulcast with Korea in October on iQiyi International app or iQ.com across 190 territories.
