Pureunggil (Korean title: 푸른길; Japanese title: プルンギル －青の道－, literally "Blue Road") is a Korea–Japan co-produced crime thriller coming to Netflix on November 20, 2026. Korean actor Son Suk-ku and Japanese actor Eita Nagayama play detectives chasing a series of murders that cross national borders.
🛣️ Plot
Bodies with twisted limbs, a mysterious message, and horrifying murders that repeat across borders. Pureunggil follows two detectives — one Korean, one Japanese — in a hard-boiled crime investigation. It is based on a manga created jointly by Korean and Japanese artists.
The poster shows the two detectives standing in night-time alleys in Korea and Japan, almost back to back, with an eerie message written in Korean and Japanese floating in the background and the tagline "A bizarre murder across borders".
