01Release Date Confirmed

The Korean film White Blast will open in theaters on November 18. Distributor Showbox confirmed the date when it released the film's main trailer on its official YouTube channel on October 20. A first trailer had appeared on the same channel at the end of September, promising a November release.

02A Station Cut Off by Snow

The story takes place at a small rural train station that a heavy snowstorm has cut off from the outside world. Kim Yun-seok plays Gap-soo, a stationmaster close to retirement, and Koo Kyo-hwan plays Hyun-taek, the newly arrived successor. When the two men find a mysterious body at the station, an unpredictable mystery begins. The official trailer sums up the situation with a line that blames everything on the snow.

03The People Behind It

According to TV Report, the film is directed by Hong Eui-jeong, whose earlier feature Voice of Silence drew attention. On October 27, Soompi shared a new poster in which Gap-soo watches Hyun-taek closely as he wipes blood from near his eye. Roh Yoon-seo is also named in the official trailer's description.
