There is a family from South Korea known as the Kims. It consists of father Ki-taek, mother Chung-sook, son Ki-woo, and daughter Ki-jeong. They are decidedly not well off, living in a small basement apartment. The dwelling is unkempt with dishes strewn everywhere and they often find themselves needing to hold their smart phones to the ceiling to get any kind of Wi-Fi reception. They are barely staying afloat by working various low-paying odd jobs. One day, Ki-woo’s friend, Min-hyuk, intends to study abroad, and gives the Kim family a scholar’s rock, which is supposed to bring them wealth. Feeling pity for his friend, Min-hyuk suggests that Ki-woo pose as a university student and take over his job as an English tutor for one Park Da-hye. The Park family is very wealthy, so Ki-woo may have stumbled into something that can help his family leave their squalid living conditions.
The year is 1951. Six years have passed since the conclusion of the Second World War, and another conflict has broken out – this time in the Korean Peninsula. North Korea, with the support of China and the Soviet Union, fights against South Korea, whose citizens are backed up by the United States and her allies. Just like in the Second World War, the army has made extensive use of the Mobile Army Surgical Hospital (MASH) – a fully functional medical unit deployed in the combat zone. The 4077th of these units is about to shaken up when its two newest surgeons, “Hawkeye” Pierce and “Duke” Forrest arrive in a stolen Army Jeep.
Osamu is a day laborer who has been forced to leave his job following a severe injury. He is a member of an impoverished family in Tokyo. He lives with his wife Nobuyo, sister Aki, nephew Shota, and grandmother Hatsue. As a way of saving money, Osamu and Shota routinely shoplift goods, using an intricate system of hand signals as a means of communication.
