"White Blast" centers around a remote rural train station trapped by a severe snowstorm. The story unfolds after Gap-soo (Kim Yoon-seok), the chief of the station, and Hyeon-taek (Koo Kyo-hwan), a newly assigned staff member, discover a mysterious corpse.
The director expressed her hope that the movie will encourage viewers to question their own perceptions and moral judgments as the plot twists and turns.
"I hope viewers will ask themselves questions like 'How could my judgment be so wrong?' or 'Is it right to root for this person?' as they watch the movie," Hong said. "Depending on their perspective, the story may look completely different.”
