White Blast (1970)

At a remote train station covered in heavy snow, a station master Gap-su is facing the last day of his life-long dedication to the station. Devastated by the sudden layoffs, Gap-su keeps waiting for his young replacement, who still hasn’t yet come. As the hush reigns throughout the station, Gap-su sees the breaking news that dozens of convicts escaped from the overturned prison bus, and just then, a young man walks into the station claiming himself as the one Gap-su has been waiting for.
