The Kim family is enjoying a private party at the Parks’s home while the Parks are away when the former housekeeper, Moon-gwang, returns. She reveals that her husband, Geun-se, is living in a secret room in the basement to hide from debt collectors. The Kims end up fighting Moon-gwang and Geun-se, and Chung-sook fatally injures Moon-gwang. The Kims lock Moon-gwang and Geun-se in the basement and hide in the house when the Parks return home early. The oblivious Parks hold a party the next day. Geun-se escapes and attacks the Kims at the party, injuring Ki-woo and killing Ki-Jung, and Chung-sook kills him. During the commotion Ki-taek snaps and kills Mr Park when Mr Park recoils from his smell. Ki-taek escapes. Moon-gwang’s body in the secret room is not found.
After recovering from his injuries, Ki-woo and Chung-sook are sentenced to probation. Ki-woo discovers that Ki-taek is hiding in the secret basement room of the Park home (the Parks themselves having sold it to new owners.) Ki-woo communicates to him that one day he’ll earn enough money to buy the home so his father can live freely, but this is just a fantasy.
