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.
