In the midst of a deluge of patients and their individual medical histories, the 4077th is out of blood. Everyone in camp is donating at 48-hour intervals when a truckload of Turkish soldiers arrives to offer their blood and save the day.
The 4077th Mobile Army Surgical Hospital is stuck in the middle of the Korean war. With little help from the circumstances they find themselves in, they are forced to make their own fun. Fond of practical jokes and revenge, the doctors, nurses, administrators, and soldiers often find ways of making wartime life bearable.
