Director: Joon-ho Bong.
An ordinary Korean family does not spoil life. You have to live in a damp, dirty basement, steal the Internet from your neighbors and interrupt with random part-time jobs.
Once, a friend of the son of the family, leaving for an internship abroad, suggests that he be replaced and worked as a tutor at a high school student in a wealthy Pak family. Having faked a diploma of higher education, the guy goes to a chic design mansion and makes a good impression on the hostess of the house. Immediately, an unusual plan for the employment of his sister comes to his mind.
