장남(1984) / The Oldest Son (Jangnam)

An engineer is finally building his displaced parents the proper house he promised them on a lot outside Seoul when his mother dies days before it is finished, while he is away supervising a factory on Jeju. Lee Doo-yong's family drama is a quiet accounting of what one generation's climb into modern life costs the people it was meant to repay.
