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.
The 4077th hosts a traditional Korean wedding, much to Frank's objections. And Colonel Potter runs into an old friend who has put his troops in jeopardy so that he could receive a promotion.
