Work in a space called the “underground” subway.
Sang-woo, who attends a business high school, enters the job market ahead of graduation.
Sang-woo, who initially thought it was a wrong school under the overwhelming weight of the hands-on machines in the school, secretly hopes to engage in a job that seems comfortable and safe among the so-called Burton Man.
Unlike those who walk on the tracks and maintain themselves, they naturally distinguish between non-regular and regular workers by looking at people who move comfortably on rides, and they also calmly say that they will be able to get full-time jobs over time.
As the title suggests, <Underground> silently shows the “work” of workers in an invisible space that enables the daily appearance of subways.
When the train comes in after the operation, workers remove the wheels and separate the accessories to repair them.
Track maintenance is only possible at dawn when there are no trains, so they work at night. The cleaner cleans up the vomit, and the driver gets off the train deep under the ground and walks off along the tracks.
But the film doesn’t just show this movement.
The orientation of the film is shown through interviews of workers inserted between labor scenes.
They argue that safe operation is not unusual at any time, citing problems such as irrationality in handling industrial accidents underground, conflicts between non-regular and regular workers, poor working conditions, and unmanned processes that cannot be excluded from driving.
Above all, we face that Sang-woo, who becomes a technology worker after generation, is us except for the very few.
It is a work that makes us all aware that we are all in the underground.
