A mother and son who defected to South Korea in 2007 run a food truck together and live under the same roof. They do not rely on each other. The son, who thinks he was brought to a strange land, resents his mother. The mother does not understand her son who does not seize his chance. She buys a pension in hopes of building a foundation for his son’s life in South Korea but ended up being defrauded. Neither Youngsoon nor his son Sosa reveal their feelings. The existence of her husband (his father) who committed suicide and her eldest son (his brother) missing in North Korea cast a dark shadow on their life, but the film never shows the two having a conversation about it. The film hints in another way that the words and actions of the two, who seem strong and firm at first glance, stem from deep wounds. Is South Korea really a land of opportunity for the mother and son who just want a normal life? A Mother Youngsoon is a work that genuinely portrays the lives of North Korean defectors through two characters, Youngsoon and Sosa, and goes beyond personal history to beg the question about public concern.​
