Mansumyeon Mugangri

A medical resident named Dong-Ha, known for his clumsy yet brilliant mind, unintentionally achieves success in a self-conducted human reproduction experiment. Eight years later, South Korea faces a national crisis due to a rapidly aging population and declining birth rates. To address this, Dong-Ha creates a set of personal rules and restarts his experiment. To secure necessary resources, he opens a small private hospital in the rural village of Mansumyeon Mugangri, which is populated mostly by elderly residents. He brings along his eight-year-old son, Gam-Nyeong. In a paradoxical turn, Dong-Ha begins committing acts of killing as part of his efforts to save the country and the human race.
