Hawkeye is the golden boy of the world press when he treats a celebrity prizefighter, 'Gentleman' Joe Cavanaugh, who has a stroke at the 4077th. Father Mulcahy finds the news hard to take, as Cavanaugh was a hero of his.
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.
