Movie Story : Ok-ja and her son Do-hyun falsely register their address in Seoul's Daechi-dong so he can attend a better school, despite their tight finances. Envious of his wealthy classmate Sang-su, who receives disability benefits, Do-hyun discovers he is not actually disabled, which exposes flaws in the state's welfare system. At university, he teams up with his friend Ji-woo to exploit government startup subsidies, deliberately failing to take advantage of the system's leniency.
