Suppression becomes harsher when it goes down to the bottom of the power structure, and conditions of survival get sterner as well. The encounter of temporarily hired science teacher Young-sook and her student So-young happens at the bottom of the power pyramid. Young-sook is eager to be a full-time employee, while her student is also eager to get a higher score. Who can blame either of the two for their secret deal? With brilliant characters and eye-catching aesthetic styles, the film elaborately deals with matters of power and survival. (Jay Sohn)
